Braeburn 1025NC Heat-Only Thermostat

The Braeburn 1025NC is a non-programmable thermostat designed for single-stage heating systems. It supports conventional heat, millivolt systems ranging from 250 to 750 mV, and 2 or 3 wire hydronic zone setups. Builders and homeowners needing simple, reliable temperature control without scheduling complexity will find it fits the job.

Sustained Operation Reliability

Permanent memory keeps all settings intact during power interruptions so the thermostat resumes correct operation immediately. Dual power from battery and hardwire sources provides continuous function even if one supply fails. A front-access reset button and low-battery indicator allow quick diagnosis without removing the unit from the wall.

Upgrade From Basic Mechanical Stats

This unit replaces older mechanical thermostats that lack adjustable temperature limits and digital precision. The jump is worth it when you need tighter temperature control for hydronic zones or millivolt heaters and want a permanent memory that survives outages. It does not serve systems requiring cooling, multi-stage heat or programmable schedules.

Highlights

  • Heat-only control for single-stage and millivolt systems
  • Works with 2 or 3 wire hydronic zone valves
  • Settings kept in permanent memory after power loss
  • Low-battery alert and front reset button simplify upkeep
  • Adjustable temperature limits prevent unwanted extremes

Questions about this item

Does the 1025NC draw enough power to need a C-wire, or can it run on batteries alone all day?

The 1025NC is dual-powered, so it can operate on batteries, hardwired power, or both at the same time.

My hydronic zone valves use a three-wire hookup — will the 1025NC connect directly to them?

Yes, the thermostat is compatible with 2 or 3 wire hydronic zone systems.

I still have a 250 millivolt heating system — will the 1025NC work with that voltage?

It supports millivolt heating systems from 250 to 750 millivolts.
