Danfoss 003N0050 | KPI 35 Electronic Room Thermostat, 5–35°C, SPDT 230V AC
Danfoss 003N0050 (KPI 35) electronic room thermostat. 5–35°C setpoint, SPDT 10(4)A @ 230V AC, surface mount, for heating/cooling HVAC zone control.

Product Overview

The Danfoss 003N0050​ is the commercial reference for the Danfoss KPI 35 electronic room thermostat​ — a bimetal-sensing, line-voltage thermostat designed for space temperature control in heating and cooling systems. It features a 5–35 °C adjustable temperature range, SPDT (Single Pole Double Throw) switch contacts​ rated at 10(4)A @ 230V AC, and is intended for surface mounting in residential, commercial, or light industrial HVAC zones. The thermostat operates on a 2-wire or 3-wire control scheme​ depending on whether it switches a pump, fan coil, or zone valve directly.

Key Features

  • SPDT Switching:​ Provides both heating (NO) and cooling/alarm (NC) contact from one device — useful for 3-wire fan-coil or heat/cool changeover control.
  • High Contact Rating:​ 10A resistive allows direct switching of small circulation pumps, zone valve motors (check inrush!), or fan relays without an intermediate contactor.
  • Simple Calibration:​ Setpoint knob with clear °C scale; no batteries or external power required (purely electromechanical).
  • Wide Application Range:​ 5–35°C span covers frost protection (5°C) through comfort heating and moderate cooling setpoints.

Applications

  • Hydronic Heating Zones:​ Switching zone valve motors (e.g.,  VG) or circulating pump relays in underfloor or radiator systems.
  • Fan Coil Units (FCU):​ 3-wire control — NO contact to heating valve / NC contact to cooling stage or fan interlock.
  • Server / Plant Room Frost Protection:​ Setting to 5–8°C to energize trace heating or space heaters.
  • Retrofit Thermostat:​ Direct replacement for older line-voltage room stats in European-style HVAC installs.
Note: The 003N0050 (KPI 35)​ is an electromechanical bimetal SPDT room thermostat. For a digital programmable / PI-controlled​ version with LCD and 0–10V/relay output, see the Danfoss RTD / ECL Comfort / Icon​ series. If you need a 2-wire NO-only (SPST) version, the KPI 30 (003N0040) is the single-pole variant. Always verify valve/pump coil inrush current doesn't exceed the 4A inductive rating before direct switching.
