Commercial Multi-Stage Thermostat
The Venstar T2800 is a slimline programmable thermostat designed for commercial HVAC systems. It supports up to three heating and two cooling stages with a 7-day schedule. The unit replaces specific Totaline models and requires a 24V common wire for operation. It is not suitable for two-wire heat-only installations.
Installation Requirements
A 24V common wire must be present at the thermostat location before installation begins. The product will not function on two-wire heat-only systems, so verifying wiring compatibility is essential. The backlit display and colour-coded keys simplify configuration once powered. Non-volatile memory retains settings during power interruptions.
Programming and Control Limits
The thermostat allows up to three occupied periods per day with holiday and energy-save modes. Set-point limiting and keypad lock restrict unauthorised adjustments. A configurable output provides flexibility for auxiliary equipment. An optional humidity module accessory extends environmental control when fitted.

Questions about this item
How can I confirm the thermostat is operating correctly after installation?
Verify the backlit display shows the current temperature, the LED indicator glows green for cooling or red for heating, and the system responds to set-point changes in each of the up to three occupied periods.
What comes in the box and what must be purchased separately?
The thermostat unit is included; a 24 V common wire is required for power and the optional Humidity Module accessory is sold separately for humidity control.
Which version should I choose if I need to replace a Totaline P374-2200 or P374-2800?
This T2800 model directly replaces both Totaline P374-2200 and P374-2800 units, providing 3-heat/2-cool staging and 7-day programming in a slimline housing.
