APPLICATIONS AND FEATURES
The T190 thermostat is a low-voltage programmable thermostat designed to control most conventional systems. It is configurable for up to two-stage heat and two-stage cool and has manual or auto-changeover modes. The thermostat is 7-day programmable, with different heating and cooling setpoints for 4 time periods per day. The thermostat can also, be set to nonprogrammable (manual) operation.
System Types (up to 2 Heat / 2 Cool)
- Gas, oil, or electric heat with air conditioning
- Heat pumps
- Heat-only, two-wire systems
- Heat only with a fan
- Cool only
Do not use systems with more than 2-stage heat and 2-stage cool, systems exceeding 30 VAC and 1 amp, millivolt systems, or hydronic systems. Power Options The thermostat will operate on either 24 VAC power or two AA alkaline batteries. The thermostat does not need batteries to
Power Options
The thermostat will operate on either 24 VAC power or two AA alkaline batteries. The thermostat does not need batteries to store user-configured settings in memory. During power loss, nonvolatile memory saves all user settings, configurations, and usage counters for an unlimited time.

INSTALLATION
WIRING AND MOUNTING
- To avoid electrical shock or damage to equipment, disconnect the power before installing this thermostat.
- Position the three switches on the back of the thermostat, according to the HVAC system being controlled and the power source.
- Connect electrical:
- If using a mounting plate: Pull the wires out of the middle hold of the mounting plate and adjust the plate on the wall or junction box.
- Loosen screw terminals, and insert wires into the appropriate terminals, then re-tighten the screws.
- Cap off all unused wires. All connections must be located in the outlet box. Conventional System Terminal Designations

The thermostat mounts to a horizontal or vertical 2×4 junction box with the use of an accessory mounting plate or may be mounted directly to the wall:
- Place the 2 wall anchors into the wall.
- Fasten the thermostat with the screws provided through the 2 mounting holes. One mounting hole is accessible through the battery compartment (located under the front cover of
thermostat). - Place two AA alkaline batteries into the battery compartment (located under the front cover of the thermostat).
Note: In these instructions, the term “Normal Mode” refers to the default thermostat display (i.e. when the user is not performing any operations). The default display shows the current time, current room temperature, day of the week, event, system mode, and program selection. Pressing the button
always takes the thermostat to Normal Mode
The installer must configure the thermostat to match the installed heating/cooling system. The Service Menu allows the installer to modify configuration variables that are not normally accessed by the end user. The configuration variables are identified by Menu Number, as listed in the “Service Menu
Functions” table.
Accessing the Service Menu
From the Normal Mode thermostat display, simultaneously Press the ▲ and ▼ buttons, and hold down for 5 seconds. This takes you to the Service Menu and menu item number
- will be flashing.
- Push PROG to scroll to the Service Menu item number to be configured.
- Push ▲ ▼ buttons to configure the selected menu item. The service menu number is always shown in the small digits; selection values are shown in the larger digits or other icons as appropriate
- To save your configuration selection and go to the next Menu Number, press PROG. Saving and Exiting the Service Menu The Service Menu exits and returns to Normal Mode after 60 seconds of inactivity or by pressing the button. Changed values are saved to permanent memory.
CHECK THERMOSTAT OPERATION
After wiring and configuration are complete, turn on the power at the main fuse or circuit breaker box. Check thermostat operation:
- Set the fan to ON. The blower should begin to operate.
- Set the System Switch to AUTO, or available selection.
- Using the ▲ button, adjust the temperature above the room temperature to cycle the heating stage(s) on. Using the ▼ button, adjust the temperature below the room temperature to cycle the cooling stage(s) on. Refer to Owner’s Manual for instructions on how to operate and program the thermostat.
Note: All menu numbers may not appear, depending upon the T190 model.
