HAI Communicating Thermostats and the Programmable Energy Saver Module (PESM) provides energy savings, comfort, and
convenience by setting the HVAC system(s) to the proper temperature based on whether you are home, asleep, away, or vacation.
The temperature can be reported as well as controlled over any telephone. A freeze alarm feature will cause a dial out if the
temperature falls below a preset level.
The HAI Communicating Thermostats are digital heating and cooling thermostats that can be controlled be the user and by remote
control. There are models for conventional single stage (gas or electric), heat pumps, and multi stage heating and cooling
systems. All models offer programmability, stand-alone operation, and robust communication to the OmniLT system.

steps, if three numeric digits are entered. The third digit adds a .5 to the first two digits, if it is anything other than zero. Enter a
leading zero, if necessary.
