Relay Modules & Retrofits
I/O Devices
I/O Devices act as an interface between an IQ controller and heating and ventilation equipment.
Overview
The Single Relay Module (SRM) enables a controller output signal to drive a single changeover relay. The 2SRM houses two single relays. The Two Relay Module (2RM) may be configured as a high/low or a raise/lower relay module by link selection. The Three Relay Module (3RM) may be configured as a Fan/Heating/Cooling sequence controller (HCM) or a 3 stage sequence controller (TRM) using the operating mode link. The Six Relay Module (6RM) converts an analogue output of an IQ controller to six stages of relay output.
