The T190 thermostat is a low-voltage programmable thermostat designed to control most
conventional and heat pump systems. It is configurable for up to two-stage heat and two-stage
cool. The thermostat is 7-day programmable. Different heating and cooling setpoints and times are
programmable for 4 time periods per day. The thermostat can also be set to non-programmable
(manual) operation.
The T190 thermostat does not need batteries to store user-configured settings in memory. During
power loss its internal memory saves the all user settings, configurations, and usage counters
for unlimited time.
