ThermaSync Defoster Control BackThermaSync 2800 M Series Modulating Defroster Controls
The 2812/2824 controls feature adjustable automatic off timing, power modulation and can be networked to allow multiple defrosters to be activated by a single switch. All controls include the defroster switch.

Automatic Timing
The length of time the defroster is on can be set to 10, 20, 40, 80, 160 minutes or manual off. This is ideal for plow trucks or other applications in which the defroster should be left on longer than the normal ten minutes.

Remote Switch Installation Options
The ThermaSync defroster switch can be mounted up to 30 inches from the control which allows for remote installation of the switch either in dash or with the under dash in the mount supplied in the 2728 Installation Pack. See below for more on the 2728 pack.

Powering Factory Rear Window Defrosters, Defoggers and Demisters
Frequently replacement windows come with a defroster but the vehicle does not have the defroster circuit needed to operate the unit. When the vehicle has a defroster but no defroster control, ThermaSync is a good choice to power OEM and factory rear window defrosters. We recommend the 2712 ThermaSync Defroster control for these applications. The 2712 ThermaSync Defroster Control when combined with the 2728 Installation Pack provides a complete solution for operating factory defrosters, defoggers and demisters.  

ThermaSync heated mirrior control and timer Powering Aftermarket Heated Mirrors
The ThermaSync defroster controls are a good companion for powering aftermarket heated mirrors independently or with Clear View defrosters. ThermaSync controls are compatible with aftermarket heated mirrors from Grote, West Coast, Sure Plus, Truck Lite, Dorman and factory heated mirrors from Ford, Chevrolet, GMC, Dodge and others.  ThermaSync defroster controls are a good addition to any heated mirror installation. 

The 2712 ThermaSync Defroster Control is the reliable relay based defroster control which features 10 minute automatic timing. Push the button and the defroster goes off in ten minutes automatically. For most applications the 2712 ThermaSync control is a good choice. If other timing options are required the 2812 ThermaSync Defroster Control features timing that can be changed in the field.

The ThermaSync 2812 is a little more complex featuring automatic timing that can be set in the field by moving small jumpers on the controls printed circuit board. ThermaSync Defroster controls are available is 12 and 24 volts.

ThermaSync Power Modulation
The 2812/2824 defroster controls can modulate the apparent power delivered to the defroster. These controls change the apparent voltage delivered to the defroster based on a jumper setting on the control. Power modulation allows for small defroster designs and prevents small defrosters from over heating. Modulation is set at the factory to match the requirements of the Clear View defroster it ships with.

The setting of 100% delivers the full voltage from the vehicle to the defroster while 3% delivers only a fraction of that voltage. 

Use with Clear View Defrosters
Each Clear View defroster has a specific modulation with smaller defrosters having lower modulation settings. The modulation requirement for a specific Clear View defroster is shown on the first page of Attachment 2 of the instructions. It is CRITICAL that the ThermaSync defroster control’s modulation setting match the requirements of the defroster it controls. 

Measuring the voltage from a modulating control is difficult as the voltage is being switched giving most multi meters erratic signals and fluctuations in the voltage display. This is normal when reading a modulating control.
