For cabinets with serial numbers TE-MD-00564 –> TE-MD-01032
The fixed thermostat, which is the small red box on the side of the heater, may require replacement overtime. We now supply a variable thermostat to replace this. This allows you to set the temperature inside the cabinet. The replacement thermostat should be installed by a competent person.
The replacement thermostat requires a bracket attaching to the back plate and two wires connecting to the existing heater.
We recommend the thermostat is set to 12*c once installed.
If you are unsure if this is the right product for you, your old heater should look like the photo below. Please contact us if you need further help.
