Diversitech t771 Non-programmable Thermostat Garage Heater

Product Description

The DIVERSITECH t771 is a non-programmable, single-stage thermostat designed for heat-only or cool-only applications where a low setpoint range is required. Its temperature control range extends down to 25 degrees F, making it well suited for environments that drop below typical residential thermostat minimums. Licensed HVAC technicians and service pros install this control primarily in commercial and residential garage heating applications, where maintaining a minimum safe temperature is the goal rather than occupant comfort conditioning. The t771 provides straightforward single-function control without the added complexity of multi-stage or programmable logic.

This thermostat is a common choice for unit heater installations in unconditioned or semi-conditioned spaces such as garages, workshops, storage facilities, and agricultural buildings in cold climates. It is designed to maintain a setpoint low enough to prevent freezing conditions without overshooting into full comfort-range heating. The single heat or single cool configuration simplifies wiring and commissioning in spaces where only one mode of conditioning is needed.

Key Features

• Low setpoint range down to 25 degrees F for cold-climate unit heater applications
• Non-programmable design for simple, reliable single-function control
• Configurable for heat-only or cool-only operation
• Well suited for garage unit heaters and unconditioned space temperature management
• Straightforward installation with minimal wiring complexity for single-stage systems

Compatibility

Designed as an OEM-style replacement or new-install thermostat for single-stage heat-only or cool-only systems, including low-voltage unit heater controls commonly found in residential garages and light commercial spaces.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with local codes and the equipment manufacturer instructions. Power down the heating or cooling system at the disconnect or breaker before making any wiring connections. Mount the thermostat on an interior wall away from direct drafts, heat sources, or exterior surfaces that could affect temperature sensing accuracy. Verify system voltage compatibility before energizing the control.
