White-Rodgers 1F95-1277 Thermostat

The White-Rodgers 1F95-1277 is a commercial-grade universal staging thermostat designed for versatile field applications, supporting up to 4 stages of heating and 2 stages of cooling. This Blue 12-inch touchscreen thermostat features auto changeover and is compatible with single-stage, multi-stage, and heat pump systems, including those with dual-fuel requirements. Installers can configure the unit for 7-day, 5+1+1 day programming, or non-programmable operation depending on the site requirements. It operates on 20-30Vac hardwire or battery power for millivolt applications. This model serves as the primary White-Rodgers 1F95-1277 replacement for several legacy units, including the 1F95-1271, 1F95-377, and 1F93-380. The 1F95-1277 wiring terminal block is laid out for rapid termination, and the large backlit display provides high visibility for setpoint adjustments between 45-99°F. With keypad lockout and programmable fan logic, it offers precise control for demanding HVAC environments.

• Universal Compatibility: Works with 2H/2C conventional and 3H/2C heat pump systems, reducing the need to carry multiple SKUs on the truck.
• Flexible Programming: Selectable 4, 2, or 0 periods per day to match residential or light commercial scheduling needs.
• Dual Power Options: Reliable hardwired 24V connection with battery backup ensures settings persist during power interruptions.
• Legacy Integration: Direct drop-in replacement for RHC-TST412MDMS and several Emerson Blue thermostats, simplifying retrofits.

Is the 1F95-1277 compatible with dual fuel heat pump systems?
Yes, this universal staging thermostat includes logic to manage dual fuel heat pump applications, allowing for seamless transitions between heat pump and fossil fuel auxiliary heat.

Can I lock the touchscreen to prevent unauthorized setpoint changes?
The unit features a keypad lockout function, which is essential for commercial settings where setpoint security is required to maintain energy efficiency.

Does this model require a common wire (C-wire)?
While hardwiring to 20-30Vac is recommended, the 1F95-1277 can operate on dual power using batteries, making it suitable for millivolt systems or retrofits lacking a C-wire.
