TLR-D5F with OPA-D5F


Fan coil unit controller with base unit and operation terminal for 3 speed fans and 1 3-point floating valve

The TLR-D5F is a stand-alone electronic single loop controller with a fan control option and one PI heating or cooling sequence. The operation terminal is called OPA-D5F. The controller includes 1 NTC room temperature sensor and 3 relays outputs to control fan speeds and 2 TRIAC outputs for floating control. A detailed adaptation to local conditions is possible with the use of a simple configuration routine. The TLR-D5F can be configured using the standard operation terminal. No special tools or software is required.

 The TLR-D5F has been specifically developed to switch larger fans with switching power of up to 10 (6) A.
