To remove the module on DIN rail, pull the tab down to release it.
Connection
The Relay Radiant Heat Control Module is a device that is connected to the Airzone Connection Bus of the control board
(Fig. 28).
Control relay specs: 24/48 Vac (voltage-free). To control elements of a greater power, it is recommended the use of contactors
in accordance with the power required. Remember to connect the neutral connector directly from the circuit to the element to
be controlled.
The SW2 microswitch configuration (zone ID) is as follows:
Example:
The relay to control a radiant element of a module with address 6 is the R1 of the Relay Radiant Heat Control Module with
the address set for the zones 6-10.
It has a 4-pin terminal to connect it to the AC unit bus of the main board. Use the proper cable:
shielded twisted pair 4 wired: 2x0.22 mm
2 +
2x0.5mm

(AWG 20 – 4 wired). Attach the wires with the
terminal screws following the color code (Fig. 29).
