The current status of a temperature zone may be displayed by selecting ' # ' (STAT) key from the main temperature menu. The status display differs depending on the temperature zone type.

When you are finished, press the ' * ' key twice to return to the top-level display.

IMPORTANT NOTES:

¾There is a 3-minute minimum on and off time for PESMs designed to prevent short cycling your HVAC compressor. If the PESM has just turned the HVAC system on or off, it will wait 3 minutes before changing it, even though the display does change.

¾If you change the Heat or Cool setback temperature on the PESM, the system will insure that there is always at least four degrees Fahrenheit difference between the Heat and Cool temperatures by altering the other setback temperature as necessary.

¾PESMs are NOT affected by All On or All Off commands.

Freeze Alarms

Thermostats and PESMs can also be used to report potential freeze conditions before damage to pipes and appliances can occur. An alarm is activated when any Thermostat or PESM detects a temperature below 40 degrees. The alarm will not clear until the temperature exceeds 45 degrees.

When the alarm is initiated, the console beeper will be turned on and an alarm dial-out sequence will be initiated after the normal dial-out delay. Both voice and digital communicator dial-outs may be used. The voice dial-out will follow the Dial Order as specified in Set Up Dial. The digital communicator will report the Freeze Alarm Code to the Central Station.

The sounder is not activated for freeze alarms (this feature must be activated by your installer).

Indoor and Outdoor Temperature

The Model 31A00-1 Temperature Sensor is used for sensing temperatures from 0º F - 120º F and 31A00-7 Extended Range Temperature Sensor is used for sensing temperatures from -40º F - 120º F. It features a new, high accuracy temperature sensor that doesn’t need calibration.

The temperature can be used to activate programs for controlling temperatures indoors and in attics, garages, greenhouses, basements, wine cellars, coolers, and freezers. 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.

Outdoor temperature zones have a High and Low temperature associated with them that can be used for control purposes. An example of this is to program the system to turn on the bathroom heat if the outdoor temp goes below 45 degrees. High and Low temperatures are changed the same way as a PESM.

When a temperature sensor is selected from the list of temperature devices, you may set a “Low” and “High” setpoint for activating programs or alarms. Enter the desired temperature then press the ' # ' key.
