EMERSON 80 Series 1F83C-11PR Thermostat | Montreal, Laval, Longueuil, South Shore & North Shore
A single-stage furnace, an old dial thermostat and the wish to turn the heat down at night: 7-day or 5-1-1 schedule, on batteries (even millivolt) or a C wire.
Quick facts
A single-stage gas, oil or electric furnace that has answered to a dial thermostat for years: that is where a simple schedule changes daily life. The 80 Series 1F83C-11PR (EMERSON’s White-Rodgers line) lowers the setpoint at night and while you are at work, then brings it back up before you get home, as you program it, with no Wi-Fi or app.
The essentials of a programmable thermostat
- Single stage: 1 heat / 1 cool, for heat only, cool only or both.
- Schedule: 7-day or 5-1-1 (the default), 4 periods per day, or non-programmable mode.
- 24 V or millivolt: on batteries, with a system from mV to 30 VAC, or hardwired at 20 to 30 VAC with a C wire.
- 4.5 sq. in. screen: backlit and high-contrast.
- Keypad and setpoint: keypad lock and setpoint limits, within a 7 to 37 °C range.
- Tidy install: built-in level and a terminal block on the subbase.
Compatible furnaces and systems
It runs conventional gas, oil or electric furnaces, and a heat pump with no backup heat, at 1 heat / 1 cool. Dual fuel needs a backup stage that it does not have. Hot water and steam do not appear on its sheet. It is not suited to baseboards, convectors, radiant ceilings, fan-forced heaters, electric floor heating or wall and ducted heat pumps. In its 2025 cross-reference table, the brand lists the 1F83C-11PR to replace the 1F80-361, 1F87-361 and 1F80-0261.
Next to its neighbours
The EMERSON 80 Series 1F83C-11NP runs the same type of system without a schedule and takes a higher load: 1.5 A per terminal and 2.5 A total, against 1.0 A and 1.5 A here. The EMERSON 70 Series 1F75C-11PR also offers a 7-day or 5-1-1 schedule and also takes 1.5 A per terminal and 2.5 A total. Its sheet lists 2 AA batteries, a filter change reminder and continuous backlight as an option with a C wire; the 1F83C-11PR sheet lists the keypad lock and setpoint limits.
How AirGreen installs it
The technician identifies your system (24 V or millivolt, with or without air conditioning) and confirms its load does not exceed 1.0 A per terminal or 1.5 A total. They level the base, wire the terminal block, choose batteries or the C wire, then set the four periods of each day with you. The first step is a free in-home estimate.
