OUTPUT MODULE - HEATER KNX HCC/S2.2.1.1

2-channel temperature controller for heating/cooling control of main circuits. Each channel has a 3-point output for mixing valve control and a 5 A relay output for circulating pump control. Each channel has input for supply and return temperature sensors and three potential-free inputs, for example for circulating pump status information. Internal calculation of mixing valve setpoint based on supply and return temperatures. Setpoint to be retrieved from the KNX system, for example from an AC/S control unit. Dual pump control possible by connecting both channels. This product description is an automated translation of the original Finnish description.
