EPH Controls A27-HW 2 Zone Programmer - 230V Wired Timeswitch for Heating & Hot Water, 5/2 Day & 7 Day Modes
EPH Controls A27-HW 2 Zone Programmer - 230V Wired Timeswitch for Heating & Hot Water, 5/2 Day & 7 Day Modes
The EPH Controls A27-HW is a 230V wired 2-zone time programmer providing independent ON/OFF scheduling for one heating zone and one hot water zone (or two heating zones) in domestic central heating systems. With three programming modes — 24-hour, 5/2-day, and 7-day — and up to 3 ON/OFF periods per day per zone, it delivers the flexible, reliable control expected on S-Plan and Y-Plan installations. A backlit LCD, copy function, holiday mode, and keypad lock make it equally installer-friendly and homeowner-friendly.
Choose from 24-hour (same programme every day), 5/2-day (weekday and weekend programmes), or 7-day (individual programme for each day of the week). Each zone is programmed independently, with up to 3 ON/OFF time pairs per day — ideal for households with varying routines.
The large backlit blue LCD displays time, date, zone status, and active programme clearly in all lighting conditions. Push-button controls and an intuitive menu structure mean programming is quick — even for homeowners unfamiliar with heating controls. The copy function duplicates a day's programme across multiple days with a single button press.
Holiday mode suspends the normal schedule for a user-defined number of days, preventing unnecessary heating while the property is unoccupied. The +1 hour boost and advance function allow manual overrides so occupants can call for heat or hot water outside programmed times — useful for occasional late nights or early mornings.
Built-in frost protection activates heating at 5°C to prevent pipe damage when the property is unoccupied in winter — even if the programmer is in holiday mode. The keypad lock prevents accidental or unauthorised changes to the programme, making it suitable for rental or managed properties.
The A27-HW accepts both surface-mount (pattress) and recessed (back-box) installation via a simple 6-terminal wiring block. Its compact 140 × 99 × 35mm profile sits neatly alongside standard thermostats, and a conventional 1- or 2-gang back box is typically all that is needed for a direct replacement on most existing systems.
The volt-free SPST outputs (230V AC, 3(1)A per channel) drive motorised zone valves or wiring centre inputs directly. The 8VA power consumption keeps standby load negligible. Compatible with virtually all domestic 230V wiring centres and zone valve actuators from leading brands including Honeywell, Drayton, and Danfoss.
