By default, the CHV-TSTATEX is configured to be powered by two AA alkaline
batteries. To extend battery life, the device also receives power from the HVAC
system by drawing a small amount of current through the heat or cool terminals. This
is known as Steal Power mode.
To enable this feature, locate the POWER slide switch inside the unit and slide it to
STEAL (This is the default factory setting on the CHV-TSTATEX).
POWER Slide Switch
NOTE: Steal Power mode will not draw enough current to cause the external heat
or cool relays to close. More specifically, when the unit is not making a call for heat,
it will draw power through the RH and W terminals. When the unit is making a call
for heat, it will draw power through the RC and Y terminals. (This will not work if
the thermostat has been wired for a cool only application.). The CHV-TSTATEX
must be wired for heat control in order to take advantage of Steal Power mode.
NOTE: In Steal Power mode, even when an auxiliary power source is available, the
unit will continue to enter a communications sleep state, waking every 30 seconds or
one minute (based on the infiNET EX Sleep Time setting) to exchange data with the
control system. Refer to “Remote Operation” on page 26 for details.
