HBX MOD-0100 Modulating Control Module

HBX MOD-0100 Modulating Control Module

The MOD-0100 expansion module is designed to be integrated with the HBX CPU-1000 HVAC controller, it is not a stand alone control device. The purpose and function of the MOD-0100 is to provide system expansion capabilities. Its primary use is to control modulating devices such as boilers and valves. For example, one CPU-1000 + one MOD-0100 can provide a total of two on/off stages and two modulating stages (when configured as a staging control). The CPU-1000 by itself does not have the capability to run modulating devices. In conjunction with the MOD-0100 the CPU-1000 can run up to five modulating devices. The MOD-0100 has a spare thermistor input with no fixed function. The installer may choose to run the spare thermistor as a room sensor or a set point sensor. The spare demand signal has no dedicated function at the time of print. The position of set point sensors (thermistors) is critical to the correct operation of the control. Pay special attention to the wiring of set point sensors in relation to actuators, pumps and multiple boiler stage relays.,/p>
