Honeywell Room Thermostat 230 Vac SPDT T6360B1028

The Honeywell Home T6360B is a mains-operated room thermostat designed for domestic central heating systems. It switches the heating circuit through a single-pole double-throw (SPDT) output rated at 230 Vac, and the same output arrangement allows it to control cooling systems as well as heating. A heat anticipator inside the unit shortens the switching cycle so the room settles closer to the set temperature instead of overshooting.

• The boiler continues to run after the room has reached the set temperature.
• Room temperature swings noticeably above or below the dial setting.
• The thermostat dial turns but the heating does not switch on or off at any point.
• Heating stays on permanently, or the system fails to respond when the dial is moved.
• Cooling mode does not engage when the thermostat is used on a cooling circuit.

• Confirm the appliance model and serial number against the compatibility list before ordering.
• Check that the existing thermostat is a 230 Vac wired unit with an SPDT output, as the T6360B is a direct mains replacement of that type.
• Isolate the heating circuit at the consumer unit before removing the old thermostat or fitting this one.
• Note the existing wiring terminals before disconnecting, so the new unit can be wired to match.
