- HAI OmniPro II Owner's Manual

The fan control on a thermostat may be switched between on and auto by selecting 4 (FAN) from the temperature menu:
Upstairs FAN
0=AUTO 1=ON
Thermostats may be switched between hold mode and the normal run mode. While in hold mode, the thermostat does not
respond to scheduled temperature changes but instead maintains the temperature at its current setting. The thermostat will then
return to its scheduled operation setting once hold mode is removed.
The hold menu is used to control hold status of a thermostat. The hold menu is entered by selecting 5 (HOLD) at the temperature
menu. Through this menu you may turn hold mode on and off.
For a heat/cool thermostat, the menu displayed is:
Upstairs HOLD
0=OFF 1=ON
Turn hold mode Off or On by selecting 0 (OFF) or 1 (ON), respectively.
For a heat/cool thermostat, the status shows the current temperature, the heating and cooling temperature setpoints, whether hold
mode is on, the system mode, and the fan On/Auto selection.
Upstairs TEMP: 78
HEAT: 70 COOL: 78

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.
