Questions about this item

Does the 1F85U-42NP thermostat require a C-wire for power?

The thermostat uses a built-in level indicator, pluggable terminals and an Easy DIY Install Wizard to simplify wiring. It controls conventional and dual-fuel systems without an outdoor sensor.

Can the 1F85U-42NP replace a thermostat that currently runs 110 V or 220 V baseboard heaters?

The product specifications state this thermostat does not work with line voltage 110 V or 220 V baseboard heating systems. It is designed for low-voltage HVAC control only.

How can I confirm the 1F85U-42NP is operating correctly after I finish the setup wizard?

The large backlit display shows the current temperature, active mode and schedule period. A filter-change reminder and keypad lock indicator also appear on-screen when those features are engaged.
