EMERSON Classic 80 Series 1F80-361 Thermostat | Montreal, Laval, Longueuil, South Shore & North Shore
Out at work all week, home on weekends, and no reprogramming when summer comes: the 1F80-361 stores its heating and cooling programs together.
Quick facts
You are at work Monday to Friday, and you do not want to reprogram everything when air conditioning season starts. The Classic 80 Series 1F80-361 (the White-Rodgers line from EMERSON) follows a 5-1-1 week and stores its heating program and its cooling program at the same time. At 1.1 in. deep, its slim housing stays discreet on the wall.
A 5-1-1 week, for heating and for cooling
- 5-1-1 programming: weekdays, Saturday and Sunday, 4 periods a day.
- Two programs in memory: heating and cooling, stored at the same time.
- Override and hold: override until the next period, or manual hold.
- Program memory: kept through a power failure.
- Power: 8 to 30 VAC 50/60 Hz or DC, 2 AA batteries included, optional C terminal.
- Backlit LCD: in a housing 6.1 in. wide by 3.8 in. high.
Supported systems
The 1F80-361 runs standard heating and cooling, or heat only, on gas, oil or electric equipment, as well as millivolt systems and single-stage heat pumps without backup heat. According to the Classic 80 instructions, it also suits hot water or steam systems, except 3-wire zoned hydronic systems. It is not for multi-stage systems, dual fuel, baseboards, electric floor heating or wall or ducted heat pumps, or for systems over 30 VAC and 1.5 A.
Two neighbouring models
In its 2025 cross-reference table, the brand lists the EMERSON 80 Series 1F83C-11PR to replace the 1F80-361. That model runs a 7-day or 5-1-1 schedule, or none, and takes setpoints up to 37 °C; its sheet lists keypad lock, setpoint limits and a built-in level, without naming hot water or steam. In the same Classic 80 series, the EMERSON Classic 80 Series 1F86-344 is non-programmable, and its sheet lists separate heating and cooling setpoints and a filter reminder.
