Honeywell T87K1007 Heat-Only Thermostat Two-Pack

This pack supplies two mercury-free round thermostats designed for heat-only systems. Each unit operates on a 24-volt three-wire connection and requires no batteries. The classic white styling fits traditional interiors while providing reliable temperature control from 40 to 90 degrees Fahrenheit.

Practical Limits of 24-Volt Three-Wire Heat-Only

The thermostats cannot manage cooling or heat-pump equipment because they lack the additional wires and switching logic those systems need. Installers must verify that the existing wiring provides a continuous 24-volt supply and a dedicated heat call wire. Buildings requiring programmable schedules or multi-stage heating will need a different control platform.

Questions about this item

Should I buy the single thermostat or the two-pack?

The product is sold as a two-pack containing two identical Honeywell T87K1007 units, so you receive both thermostats in one purchase.

What does the 40F to 90F temperature range mean for daily use?

You can set the dial anywhere between 40 and 90 degrees Fahrenheit; the thermostat will call for heat whenever the room temperature drops below your chosen set point.
