8 relay module with pump output

This module is designed for the control of electrothermal or other types of actuators in radio heating/cooling systems for domestic or office environments.

It has 8 independent channels, each of which can be associated with a wireless thermostat or chronothermostat.

The module also has an auxiliary relay for controlling the circulation pump or boiler. Each thermostat periodically transmits a command via radio containing the temperature and setpoint detected in the room. The radio commands are received by an active antenna which sends the information via wire to the DLP841M module which carries out the adjustment and activates or deactivates the output relay for the actuator associated with the thermostat.

The module is equipped with Summer/Winter input and global standby. The output actuators are powered by 230V~, alternatively they can be powered by an auxiliary voltage (24V~). The control unit is able to drive both normally closed and normally open actuators. Up to 10 DLP841M modules can be connected in cascade to form a multi-channel system connected to a single antenna.
