Heat-only thermostat for simple heating control

The Honeywell TH1100DV1000 is a non-programmable vertical thermostat designed for heat-only HVAC systems. It shows the ambient temperature at all times and lets you adjust the setpoint with one touch. A backlit display makes readings clear in low light.

Suits basic heating setups without cooling

This unit works for homes or small commercial spaces that need only heating control and no scheduling. Built-in compressor protection helps prevent short-cycling of the heating equipment. Buyers who need cooling control, multi-stage heating or programmable schedules should look at other models.

Operating range 40 °F to 90 °F

The thermostat accepts heat settings from 40 °F to 90 °F (4.5 °C to 32 °C). Setting the temperature within this range ensures the device can call for heat correctly. Verify your system requirements match these limits before installation.

Questions about this item

What heating-only HVAC system voltage and wiring does the TH1100DV1000 require to operate?

The thermostat controls a heat-only system and shows the setpoint with one touch; verify your wiring matches a heating-only configuration before installing.

Will the TH1100DV1000 replace an older mechanical thermostat on the same two heating wires?

Yes, it fits the same wall opening and uses the existing heating wires; the backlit display then shows the measured temperature continuously.

How do I confirm the TH1100DV1000 is regulating heat correctly after wiring it up?

The backlit display shows the ambient temperature at all times; when the setpoint is raised above the room temperature the heating should activate and the display will reflect the change.
