Control unit for actuator in low temperature - 2

Adjustment Control Units Radiant Panels FIXED POINT OR WEATHER COMPENSATION CONTROL FOR HEATING AND COOLING WITH MODBUS-RTU REMOTE MANAGEMENT OPERATION The control units are used in modern heating and cooling systems equipped with floor, wall or ceiling radiant panels. Once the motorised valve has been installed in the system, it is possible to select the type of operation, enabling or disabling the various functions. HEATING Fixed-point regulation: the setpoint temperature for winter heating and summer cooling is set by means of the actuator keyboard and display. The motorised valve is...
