EMERSON 70 Series 1F75C-11NP Thermostat | Montreal, Laval, Longueuil, South Shore & North Shore
No schedule for your tenants to learn: one setpoint set by hand and a filter reminder on the display, for a furnace or central air.
Quick facts
Own a duplex and need a new thermostat in every unit? Or home most of the day, so a schedule would never get used? The 1F75C-11NP (EMERSON’s White-Rodgers line) holds the temperature you pick, with no periods or days to set.
One setpoint, set by hand
- Non-programmable: nothing to learn; raise or lower the temperature and that’s it.
- Filter reminder: the display reminds occupants to change the filter.
- Power of your choice: 2 AA batteries, for systems from millivolt up to 30 VAC, or hardwired at 20 to 30 VAC with a C wire.
- Lighting: large backlit display; continuous backlight is an option with a C wire.
- Setpoint: 7 to 37 °C (45 to 99 °F).
Compatibility
The 1F75C-11NP runs a conventional millivolt or 24 V system, gas, oil or electric, whether heat only, cool only or both. It also handles a central heat pump without backup heat (1 heat, 1 cool). It cannot run dual fuel, which needs a backup stage. Baseboards, convectors, fan-forced heaters, electric floor heating and wall or ducted heat pumps are outside its scope as well. As for hot water or steam systems, its spec sheet does not name them.
Programmable or not, 70 or 80 Series
If a schedule appeals to you after all, look at the EMERSON 70 Series 1F75C-11PR: 7-day or 5-1-1 programmable, 4 periods per day, and identical otherwise. The EMERSON 80 Series 1F83C-11NP, also non-programmable, runs the same systems with the same load rating; its sheet lists a high-contrast backlit display, while the 1F75C-11NP sheet lists the filter reminder, the built-in level and continuous backlight as an option with a C wire. In its 2025 cross-reference table, the brand lists the 1F75C-11NP to replace the EMERSON Classic 70 Series 1F78-144.
Installed by AirGreen
In a plex, putting the same model in every unit gives all tenants the same control. At the free in-home estimate, we check for a C wire: without one, the thermostat runs on 2 AA batteries; with one, it can be hardwired and keep the display lit continuously, as an option. We set it for one heating and one cooling stage and, if the old thermostat marked the wall, suggest the F61-2663 wall plate, sold as an option.

Winter, Rate Flex D and rebates: what this thermostat changes
With Hydro-Québec’s Rate Flex D, electricity costs less most of the winter and more during a few peak hours. Turning the setpoint down a few degrees during those hours is what counts.
