Heater wiring schematic diagrams
The HEATSTRIP
®
heater is required to be fitted with an "ON/OFF" isolation switch and can also be controlled with the use
of a timer type control. It is recommended to use the TT-MTM Wall Controller for maximum performance and control
options. Ensure the unit is turned OFF after use.
For direct wiring to the controller, the maximum is one heater unit unless it is two THH1500A.
For multiple units from one wall controller it is recommended to talk your electrician who will use a relay or contactor.
