Our heat mat thermostat is digital for greater accuracy.
- Water-resistant stainless steel temperature probe
- Digital temperature control
- Provides constant optimum temperatures for specific crops
- Controls temperature in colder or warmer environments
- LED mode indicator lights; 3-prong grounded plug
- Compatible with all Hydrofarm heat mats
- Controllable range from 68 to 108 degrees Fahrenheit
- Celsius or Fahrenheit read-out (press Up or Down button to change)
- Max current: 8.3 amps/1000 watts
E1: temperature is too low, has exceeded the range limit; or the temperature probe open (break).
E2: temperature is too high, has exceeded the upper limit of the range.
E3: Short-circuit for temperature sensor (probe)
Can the digital heat mat thermostat adjust its setpoints above or below the factory programmed 68 and 108 degrees Fahrenheit?
No. You cannot adjust above or below these setpoints.
Will the digital heat mat thermostat work on a modified sine wave inverter?
No, doing so will damage the thermostat and disrupt temperature control of the heat mat.
How can I change the Fahrenheit/Celsius setting on the MTPRTC heat mat thermostat?
If the unit is on Celsius and you want to change to Fahrenheit, press and hold the down arrow for 3 seconds. If the unit is on Fahrenheit and you want to change to Celsius, press and hold the up arrow for 3 seconds.
Can you plug more than one heat mat into a temp controller?
Yes, it is possible with a power strip but there is only one temperature sensor probe for the thermostat. The additional heat mats will not function independently, they will either all be on/off depending on the temperature at the sensor probe.
What happens to the setting on my MTPRTC if the power goes out?
The MTPRTC will remember its setting if power is lost. If the unit is reset for some reason, the default setting is 80F.
What do the error codes mean on my Heat Mat Thermostat?
E1: temperature is below the low limit. Or the temperature sensor has an open circuit. E2: the temperature sensor has a short circuit. E3: temperature is above the high limit. To reset the MTPRTC: Unplug the unit and then while pressing the set button, plug the unit back in.
