TLR-D42 with OPA-D42
Fan coil unit controller for 3-speed fans and 2 modulating actuators.
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.
1 or 3 speed air handler units or fan coils, cooling and/or heating, for 2-pipe or 4-pipe systems with one or two modulating valves; and/or one ON/OFF control (electrical heat, gas heat, hot water spring return valve, etc).
VAV units with heat and cool air supply (auto change-over), fan powered option; local heating coil (electrical, hot water coil, etc.).
- Temperature control for 2-pipe and 4-pipe fan coil systems.
