The PESM (Programmable Energy Saver Module) is used to override existing thermostats for set-back control. It can also be used for sensing and controlling other temperatures, such as attic fans, garage fans, greenhouses, basements, wine coolers, humidors, etc. Can also be used to control spa heaters with remote temperature sensor. The PESM reports temperatures to the controller, and has a low voltage relay and LED indicator for control. The PESM doubles as a freeze sensor, which can cause the controller to dial out in the event of a furnace failure.

The Model 31A00-1 Indoor/Outdoor Temperature Sensor is used for sensing outdoor or indoor temperature. It is coated with a sealant to withstand outdoor moisture and features a new, high accuracy temperature sensor that doesn’t need calibration.

The temperature can be used to activate programs for controlling temperatures in attics, garages, greenhouses, basements, wine cellars, and coolers. The temperature can be displayed on the console or spoken over the telephone. It can also report, log, alert, or generate an alarm if the temperature reaches freeze conditions or if the temperature goes above the high setpoint or drops below the low setpoint programmed in the system.

The Model Model 31A00-2 Indoor/Outdoor Temperature Sensor is used for sensing outdoor or indoor temperature. It is coated with a sealant to withstand outdoor moisture and features a new, high accuracy temperature sensor that doesn’t need calibration.

The temperature can be used to activate programs for controlling temperatures in attics, garages, greenhouses, basements, wine cellars, and coolers. The temperature can be displayed on the console or spoken over the telephone. It can also report, log, alert, or generate an alarm if the temperature reaches freeze conditions or if the temperature goes above the high setpoint or drops below the low setpoint programmed in the system.

The Model 31A00-2 includes a Humidity Sensor that is used for reporting the outdoor or indoor relative humidity from 0 to 100 percent. High and low humidity limits can be set for taking action (i.e. turning on the bathroom vent fan, running a/c in de-humidification mode, turning on humidifier in heating mode, etc.) or reporting high or low humidity conditions in homes, greenhouses, wine cellars, coolers, humidors, etc. Controlling humidity is particularly helpful in combating the growth of mold in vulnerable areas of the home, such as bathrooms, basements, attics, etc.

The 14A00-8 is a temperature sensor used to monitor the temperature of pools, spas, aquatic ponds, and greenhouses. The temperature sensing device is potted in a stainless steel probe. It is designed specifically to monitor water temperature from the return/source and then report that information back to an HAI Omni Family controller. Supplied with stainless steel mounting screws and waterproof connectors.
