TLR-D5P with OPU-D5P


Heat pump and package unit controller

The TLR-D5P is a stand-alone electronic package unit controller with one control loop. The TLR-D5P includes one internal NTC temperature sensor, one open/contact or external NTC temperature input and five binary outputs (relays).

A detailed adaptation to local conditions is possible with the use of a simple configuration routine. The TLR-D5P can be configured using the standard operation terminal. No special tools or software is required.

The TLR-D5P has been specifically developed to switch larger loads with switching power of up to 10(6) A for each binary outputs.
