The TLR-D42 is a stand-alone electronic single loop controller with a fan control option and one PI heating and cooling sequence. The controller includes 1 NTC room temperature sensor, 3 + 1 relays outputs and two analog outputs. A detailed adaptation to local conditions is possible with the use of a simple configuration routine.
The TLR-D42 can be configured using the standard operation terminal. No special tools or software is required.
The TLR-D42 has been specifically developed to switch larger fans with switching power of up to 10 (6) A.
