TPRIII E Electronic rotary thermostat
Improved economy may be achieved by limiting the thermostat rotational
range, by means of the mechanical ‘peg and hole’ feature hidden beneath
a removable cap on the thermostat knob.

Product selector
The TPRIII E electronic panel heaters feature highly accurate
electronic thermostats (+/-0.3
O
C), providing superior comfort
and operating efficiency.
As the room temperature nears the desired set point, power to the
elements is reduced. The room temperature is closely monitored to an
accuracy of less than 0.3ºC, minimising overshoot and temperature drift,
resulting in better energy efficiency and user comfort.
