Power consumption depends on what type of engine heater and interior heater you have. An engine heater for a regular car uses between 300-600W, while an interior heater uses between 800W and 2100W. The battery charger used in WarmUp uses about 60W. A 16-ampere fuse (about 3600W) will cover nearly potential all uses.
Yes. Contact your preferred dealer or workshop and they can assist you in installing a battery charger. You can also install a control unit so that you can control your system from your mobile phone. You can also use a SMARTSTART, which uses a remote control.
Engine heater
By going here you can find the right engine heater by using your registration (license plate) number or by selecting the make and model of your car.
Heating the engine will start having noticeable benefits from +10 °C and below. An engine heater raises the temperature of the engine by 20-35 °C. This is true no matter what the starting temperature of the engine is. If the outside temperature is -10 °C, the engine temperature will be raised to between +15 and +30 °C.
Yes, a contact heater warms up the engine just as efficiently as a hose heater, only by heating the engine block instead of the coolant. In older vehicles this lead to the air inside the car taking longer to warm up than in cars with hose heaters. However, this has nothing to do with how warm the engine is. The temperature of the air in the internal heating system is not a valid measure of how efficiently the engine is being heated.
In modern vehicles, valves have been installed to prevent heat from the coolant from being used to heat the interior of the car until the engine is sufficiently hot, even if you’re using a hose heater. The important thing is that the engine reaches its ideal working temperature as quickly as possible.
The best way to ensure a warm and comfortable interior is to install a Termini™ II cabin heater or a full WarmUp system.
You may have a contact heater. The contact heater warms up the engine block and the motor oil, and is a the best solution for many cars. If that is the case, the air from the heating system will not be warm when you start the car, even if the engine heater is working. You can check to see if the engine heater is working by carefully feeling the engine block itself. DO NOT TOUCH THE ENGINE HEATER! It will become very hot when on.
If your are certain that you don’t have contact heater, or if the heater is not working, contact your dealership or auto repair shop.
- A) Ensure that the settings in your control unit are correct. Check the User Manual if necessary.
- B) There may be too little coolant. Check your level and refill if necessary. Vent the system.
- C) The engine heater may be installed incorrectly or may be malfunctioning. Check the heating element with an Ohm meter or an engine heater tester.
- D) The control unit is not connected properly.
DEFA app
This is an autogenerated text from Google Play Store; however, the message is wrong.
Try the following:
– Download the app from https://play.google.com/store/apps on a browser on your phone, not from the Google Play app.
– Go to Settings->Apps->All Apps, find Play Store there, clear its data and cache, do the same with Play Services to see if this solves the issue.
– Data and GPS may have to be enabled before downloading. This is because Bluetooth requires GPS to work on Android.
If none of these approaches work, a factory reset of the phone should solve the issue.
Link is a subscription service that lets you control your WarmUp system, wherever you may be. With Link, you will also receive alerts if your car is moved or stolen. Bluetooth control is free of charge. However, you will only be able control your system within a limited distance from the car. You will not be able to receive theft alerts with the Bluetooth solution.
This may be caused by a ground fault. Check to see if the connection is properly grounded. The problem may be caused by the charger or the relay. Contact support if the problem persists.
There are several possible explanations for this:
– When the when the preheating time is set to “auto”, the system will only start heating if the outside temperature is below +10°C.
– There must be power in the outlet the cable is connected to. If there’s no power, or if the circuit breaker has been triggered, the system will not start.
– If the vehicle was driving at the time when heating should have started, that heating period will be cancelled.
If the WarmUp slider is A) set to “TIMER” within a preheating time, and B) preheating duration is set to “auto”, the system may need som time to detect temperature conditions and decide weather to start heating. When the system is set to “auto” heating will only start if the temperature is below +10°C. This only applies when the slider is set to “TIMER” after a planned preheating period has started.

WarmUp Bluetooth®
The app is available for iOS and Android. Refer to the App Store or Google Play to see which Android and iOS versions that are currently supported. Please note that OS requirements are subject to change without notification.
Older Android devices may have trouble reconnecting with the Bluetooth® Hub, and that new pairing may be required.
No, you do not need to be logged in to a DEFA account to use to WarmUp Bluetooth®.
The effective range of Bluetooth control is typically limited to “in and around your car”. Furthermore, the effective range is dependent on installation location, phone hardware, surroundings, other types of radio signals and so on.
Location data (GPS) is used for Bluetooth scanning and background connectivity due to a security feature in Android 6.0 Marshmallow and newer. The app doesn’t use Location information for anything, but it must get this permission so that Bluetooth can work properly.
The Bluetooth® Hub must be paired with your phone via the DEFA app, not via the Bluetooth settings on your phone. Open the DEFA app – Locate the option “new device” and follow the on screen instructions.
Answer 1:
he Bluetooth® Hub must be put in paring mode before pairing. In recent Bluetooth® Hub software (build number 413 and higher), this is done by plugging the 120/230V AC power cable to the car and the power outlet. If the power cable is already plugged in when pairing starts, it must be unplugged for 10 seconds before the Bluetooth® Hub registers that it has been unplugged. There must be power in the outlet for the Bluetooth® Hub to go into paring mode. Bluetooth® Hub will not go into pairing mode if another phone is already connected.
Older software versions of the Bluetooth® Hub have a different pairing procedure:
– Software build number 363, 379 and 388: Plug 120V/230V power cable + start the engine once
– Software build number 331: start the engine twice
This pairing logic history is why the pairing instructions in the app is so comprehensive; the app doesn’t know what software the Bluetooth® Hub has, so we need to cover all versions.
NOTE! The first time an updated app is connected to the Bluetooth® Hub, the latest software version will be downloaded to the Hub. The Hub is then updated with the newest paring procedure, and this must be used during the next pairing.
An alternative method to put the Bluetooth® Hub in paring mode, is by restarting the Hub. This can be done in two ways:
Alternative 1:
Unplug the power cable from the vehicle. Remove the fuse on the cable that runs from the vehicle battery to Bluetooth® Hub (often via the DEFA charger). Reinsert the fuse after a few seconds.
Alternative 2:
Disconnect the screw connector on Bluetooth® Hub, then reconnect.
Answer 2
– Bluetooth must be enabled on your phone.
– Make sure nobody else is connected with your Bluetooth® Hub (e.g. another family member). Bluetooth® Hub will not go into pairing mode when another device is already connected.
– Go back to search menu and start search again.
– Try a different phone. By pairing with a different phone, you can make sure that the error is not being caused by the phone.
– If the phone still doesn’t reconnect with the Bluetooth® Hub as it should, please contact your DEFA dealer.
Answer 3
If you get stuck and are not able to pair, start all over by doing the following:
– Make sure the app is the latest version
– Remove the Bluetooth Hub from the device list in the app
– Remove the Bluetooth Hub from phone settings/Bluetooth
– Restart the phone
– Turn Bluetooth off/on
– Pair again
The Bluetooth® Hub will stay in pairing mode for 1 minute or until a phone is paired/connected. In older software (build number 388 and lower), the Bluetooth® Hub goes into pairing mode for 5 minutes (first time only).
There may be several solutions:
– Make sure you have the latest app installed on your phone. The latest app may contain a new software that will be installed on your Bluetooth® Hub. If another user has updated the Bluetooth® Hub to the newest software, you also have to update your app to communicate with it.
– Only one phone can be connected to the Bluetooth® Hub at a time. Make sure nobody else is connected with your Bluetooth® Hub (e.g. another family member.
– Phones with Android version 6 or later must have positioning enabled for Bluetooth to function.
– It is the phone (not the app) that handles Bluetooth connections. Some phones/OS doesn’t always manage to reconnect automatically. Possible solutions are:
- Turn Bluetooth off and on again, let the phone finish its search for nearby devices
- Restart the app
- Restart the phone
- In the phone settings, enable “visible to all nearby Bluetooth devices” may improve connection. Note: the wording may vary from model to model.
– Check that the memory is not full. In some phones it may need to be emptied at regular intervals. In Android phones this can be done by in by going to Settings > Apps > System apps > Bluetooth > Storage > clear cache (wording and menu structure may not be identical in all Android versions). A more drastic solution is to restore factory settings on your phone. This will remove all existing data and settings on your phone.
– Some phones have dedicated apps for battery management. When your battery is low, these may disable Bluetooth to conserve power. Check the settings on your phone.
– Try pairing with a different phone to make sure that the error is not being caused by the phone.
– If the phone still doesn’t reconnect with the Bluetooth® Hub as it should, please contact your DEFA dealer.
Only one phone can be connected to (control) the Bluetooth® Hub at a time. The first phone that comes into range of Bluetooth® Hub will connect automatically (if Bluetooth is enabled).
The Bluetooth® Hub has a “whitelist” of 5 phones. When the 6th phone is paired with the Bluetooth® Hub, the 1st phone that was paired with the Hub will be deleted from the whitelist.
Turn Bluetooth off and on again, and software update should start again. If you have an iPhone with iOS 11 or newer, you must stay within range of the Bluetooth® Hub all until the software update is completed. If you go out of range before update is finished, you may have to turn your phone off and on for Bluetooth to function again.
This alarm will be activated if the 120V/230V ac power cable is connected to the vehicle and the mains when you start the car. Your phone must be connected to the Bluetooth® Hub. The phone will give emit an alarm sound and generate a notification to remind you that you should disconnect the cable before you start driving.
There are several requirements that must be fulfilled for the ac power cable alarm to be generated:
– The phone must be connected to the Bluetooth® Hub (connection time depends on the phone model/version)
– The DEFA app must be running
– The app must be allowed to send you notifications (phone settings)
– The app must have access to play the alarm sound (phone settings) and the phone volume must be on and sufficiently loud.
– There must be power in the power outlet the ac cable is plugged into
– On iPhone, if the app is open (not in the background), there will be no sound, only a message
– If the user has an Apple Watch connected to the iPhone, there may be no sound at all
Note! DEFA is not liable for any damages that may occur as a result of moving the vehicle while the power cord is connected.
The temperature sensors are placed in different locations, which may result in different temperature readings.
SmartStart™
Make sure you are using the correct batteries. The SmartStart remote requires 6V Lithium batteries.
A) If your SmartStart™ has been subjected to cold, it might tell you to replace the battery even though you have just inserted a new one. To resolve this issue, allow the batteries to heat up to room temperature.
B) Make sure that you have inserted a Lithium battery of the specified type; DURACELL 28L or SANYO 2CR- 1/3N
A) Check to see if the Date and Time settings are correct.
B) Ensure that the correct weekly program is selected.
