Alpha Programmable Room Thermostat Easy-Stat RF 7.2000050

The Alpha Easy-Stat is a programmable room thermostat supplied by Alpha for use with its CD28C Extra, HE25 and HE33 boiler ranges. It works alongside a receiver that is installed inside the boiler control panel, and the two communicate over an 868 MHz radio frequency link. The thermostat sets the room temperature and the heating schedule, and passes demand to the boiler through the receiver.

• The boiler no longer responds to calls for heat from the thermostat
• The thermostat loses its RF link with the receiver in the boiler control panel
• The display goes blank, dims or shows incomplete segments
• Room temperature readings drift noticeably from the actual room temperature
• Schedule or setpoint changes are not held

• Check the GC number on the appliance data badge against the compatibility list.
• Confirm the existing part number; earlier numbers 6.1000210 and 6.1000250 are listed for this application.
• The receiver is installed into the boiler control panel, so refer to the boiler installation manual for guidance.
• The thermostat must be sited approximately 1.5 m from the ground, away from direct sunlight, heat sources, draughts, curtains and furniture.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
