Quick Summary
The HTW-WF06-NV1 Gas Boiler Room Thermostat is designed for residential gas boiler heating systems. It controls heating equipment through a non-voltage dry contact output. The thermostat supports stable temperature sensing and programmable heating control to maintain comfortable indoor conditions.
This page explains how the Gas Boiler Room Thermostat works in home heating installations. It introduces the main control functions, wiring reference, and technical parameters. Installation notes and safety features are also included. OEM and ODM options for the Gas Boiler Room Thermostat may also be discussed.

Key Features
(The main control functions and their practical value in heating systems.)
1. Gas Boiler Heating Control
The Gas Boiler Room Thermostat supports gas boiler heating control with a 3A switching capacity. The thermostat sends control signals through a non-voltage dry contact output. This design allows safe integration with many residential boiler systems.
2. Non-Voltage Output Terminals
The thermostat provides one pair of non-voltage output terminals. These terminals allow the thermostat to control boiler start and stop signals safely. This configuration improves compatibility with many heating installations.
3. Programmable Heating Schedule
The Gas Boiler Room Thermostat supports programmable heating schedules. Users can set several heating periods each day. Different temperature levels can be applied to different time periods.
4. Energy Saving Mode
Energy saving mode reduces heating demand during inactive periods. The Gas Boiler Room Thermostat maintains a lower temperature setting automatically. This function improves heating efficiency and reduces unnecessary energy consumption.(If you need Wifi function, click here)
5. External Sensor Protection
The thermostat supports connection with an external temperature sensor. The sensor continuously monitors the heating system temperature. This protection helps prevent overheating and ensures safe and stable operation.
