Room Controller TRC-3A
Produal TRC-3A
Room controller for EC fan with two proportional valves for climate control, featuring a modern 3.5" color touchscreen interface.
The TRC-3A series controllers have been designed for climate control in room spaces with modern sharp slim line 3.5" colour touchscreen interface
The controllers have up to two heating and cooling temperature control stages, fan speed control, optional CO2 level and humidity control. The units can be in various climate control applications fan coil units, chilled ceiling and zone heating/cooling systems.
The TRC-3A controllers have 3 x analogue 0-10V outputs, two external sensors inputs and one digital input. The controller offers PI-control for accurate energy efficiency.
The devices are available with both Modbus RTU and BACnet MS/TP communication.
