INTRODUCTION
The TOTALINE Universal Application programmable thermostat
can be configured for both AC and HP applications. Both modes
are dual--powered, operating from either 24VAC or two alkaline
AA batteries. Configuration and program schedules are stored in
non--volatile memory, preserving this information during power
loss and battery removal. Features include simplified 5/2
programming, large backlit display, and modern styling.
When AC application is selected, one stage of heating and one
stage of cooling are provided.
When HP application is selected, two stages of heating and one
stage of cooling are provided.
INSTALLATION CONSIDERATIONS
The P710U--21PHP, whether configured for A/C or HP
application, may be wired with or without connecting a common
wire between the indoor equipment and the thermostat. However, it
is recommended to use a common wire whenever possible.
Without a common wire, batteries must be installed. However,
battery power will be supplemented by “power stealing.”
This means the thermostat will steal a small amount of power from
the equipment to which it is connected. This will also keep it
powered while changing the batteries.
NOTE: Not all HVAC equipment is compatible with
power--stealing type thermostats. Consult the system equipment
Installation Instructions before applying this thermostat in a power
stealing manner.
If both batteries and 24VAC operation are used (batteries installed
and the common wire connected), indefinite clock operation is
provided. The battery will be used only during AC power loss,
preserving battery life.
