For a heat or cool thermostat, the status shows the current temperature, the temperature setpoint, whether hold mode is on, the
system mode, and the fan on/auto selection.

Programmable Energy Saver Modules (PESMs)
The PESM is used when you are have any thermostat, other than a HAI Communicating Thermostat, and would like to control
your heating and cooling system with the OmniPro II system. The PESM is a temperature sensor and control relay in a small
enclosure that mounts near your central heating, ventilation, and air conditioning (HVAC) system thermostat. The PESM allows
the OmniPro II to read the temperature of the area that the HVAC system controls. When you are away or asleep, the PESM can
be set to allow the temperature to drift higher or lower to reduce the operating time, hence saving energy dollars.
The PESM provides an energy saver function. When the energy saver is on, the HVAC system is set back, meaning that the
temperature is allowed to rise or fall to an energy saving level. When the energy saver is off, your thermostat operates normally.
Your thermostat should be set to the desired comfort temperature. Only when the energy saver is on will the temperature be
allowed to deviate from your normal thermostat setting.
There are three temperatures associated with each PESM:
Temperature
- this is the air temperature read by the PESM.
Heat temperature
- the air temperature will be allowed to fall to this temperature when the energy saver is on.
Cool temperature
- the air temperature will be allowed to rise to this temperature when the energy saver is on.
The following control actions are allowed on PESMs:
• Turn Energy Saver On and Off
• Turn Energy Saver On and Off for a specified time
• Set heating setpoint
• Set cooling setpoint
You can turn the energy saver on, off, use a timed on/off, and change the Heat and Cool temperatures from the console or by
telephone. Commands can also be programmed so that they occur by time schedule or by event, such as security mode change.
For example, the system can be set up to turn the energy saver(s) On and make the Heat setback temperature 65 degrees and the
Cool setback temperature 80 degrees when the alarm system is put in the Away mode. Another program can turn the energy
saver(s) off (to resume normal operation of the HVAC system) at 4:30 P.M. on weekdays to make the house comfortable before
arriving home. Different setback temperatures could be set for the Night mode.
NOTE: To set up your thermostat for use with a PESM, set it in the appropriate mode and set the temperature to your preference.
Your heating and cooling system will always be off if you set your thermostat to Off mode. The PESM cannot turn it back on.
The PESM cannot make your system cool below the thermostat's cool setting, or heat above the thermostat's heat setting.
Control actions for temperature sensors:
• Set low setpoint
• Set high setpoint
To enter the temperature menu, from the top-level display or from the main menu, press the 5 (TEMP) key on the console keypad.
You will be prompted with the first named temperature zone (i.e. Upstairs). The temperature zone can be specified by entering
the temperature zone number followed by the ' # ' key, or by pressing the arrow keys to scroll through the list of temperature
zones. Press the ' # ' key when the desired temperature zone is shown.
