Drayton Wiser Smart Heating System Installation Guide
Welcome!
Save this guide for future reference. If you are replacing an existing controller/programmer and don't need to make any wiring changes, simply remove the old product and fit your new Wiser HubR to the existing wallplate. For new systems or re-wiring, please contact a qualified installer.
❗ IMPORTANT: Do not attempt to install this product if you are not familiar with installing mains-powered electrical appliances. Always switch off the mains before removing a controller and never fit it to a live wallplate.
Installation Steps
Step 1: Mounting the Wallplate
The ideal location should have reasonable lighting, good access, no condensation, no extremes of temperature, and a supporting surface that fully covers the back of the unit.
Option 1: Fitting a New Wallplate
Position with 70mm clearance to the right, 25mm above, and sufficient room to access securing screws underneath. Fix, with terminals at the top, either direct to a flat wall using wall plugs and No. 6 x 1" (25mm) woodscrews, or on a flush mounting single conduit box type UA1 (BS4662) using M3.5 x 14 bolts. Fit the Wiser HubR onto the wallplate and tighten securing screws. Check the 3A fuse and switch on the mains.
Option 2: Using an Existing Industry Standard Wallplate
Loosen securing screws on the old controller/programmer and unplug it. Check for 70mm clearance to the right and 25mm above the wallplate. Check the wiring diagram for your product model to compare terminals and, if necessary, change the wallplate wiring. Fit the Wiser HubR onto the wallplate and tighten securing screws. Check the 3A fuse and switch on the mains.
❗ DO NOT use a surface mounting box as the wallplate is not designed for this purpose.
Note: Ensure the HubR is installed in a position with Wi-Fi coverage.
Step 2a: Wiring - Wallplate
❗ Make sure mains input has a 3 amp fuse. ⚠️ CAUTION! Before installation, make sure the mains supply is switched off!
The Wiser HubR is double-insulated and needs no earth connection, but an earthing continuity (loop) terminal is provided for convenience.
Note: If there is an existing wired thermostat, it must be completely disconnected (remove thermostat wires from the wiring centre). A link must be inserted between the terminals where the thermostat common and call for heat wires are located in the wiring centre.
For surface wiring, snap out the cable entry strip on the bottom edge of the wallplate.
Wiring Configurations:
- One Channel (WT714R and WV714R): Note that the output contacts are voltage-free*. Power needs to be supplied to Terminal 1, either by linking from Terminal L or from a separate supply with a 3A fuse. (*Not SELV - Fixed wiring only, to comply with current IET regulations.)
- Two Channel (WT724R and WV724R): Standard configuration.
- Three Channel (WT734R): Make a note of which circuit is connected to CH1 and CH3 respectively, as this information is needed later during commissioning when room thermostats are added.
Note: After wiring, clip on the unit and tighten the securing screws. Check the mains input has a 3A fuse, and switch on the mains.
Step 2b: Wiring – Boiler with Communication Module Interface
If your boiler supports a Communication Module, follow these instructions:
- Remove the Communication Module cables from the existing controller/thermostat.
- Remove the Communication Module from the rear of the Wiser HubR.
- Wire the Communication Module cables into the Communication Module (cable orientation does not matter).
- Replace the Communication Module into the HubR.
- Wire L & N on the wallplate from a separate supply with a 3A fuse.
- Mount the HubR on the wallplate.
Note: The communication module works only with Wiser Kit 1 systems (heating only). It will not work on systems with a separate hot water cylinder (Kits 2 and 3), even if the communication module is present.
Step 3: Testing the System
Heating and Hot Water Buttons
- Heating Override Button: Pressing and holding the Heating button for >3 seconds turns on heating for 2 hours. The Heating LED will flash green. Press again to turn off. The system will then revert to normal control. A solid green LED indicates heating is on.
- Hot Water Override Button (WV724R, WT724R & WT734R only): Pressing and holding the Hot Water button for >3 seconds turns on Hot Water for 1 hour. The Hot Water LED will flash green. Press again to turn off. The system will then revert to normal control. A solid green LED indicates hot water is on.
Tip: These override features can be used to 'test' an installation prior to adding any devices.
Note: The heating and hot water button override states are not shown in the Wiser app. They act as a fallback state.
Connection Charts
❗ Always switch off the mains before removing the Wiser HubR – and never fit it to a live wallplate!
Make wiring connections as shown in the charts for your appropriate system. Arrowed numbers relate to the junction box.
* Consult boiler handbook for details of pump overrun wiring.
Single Zone CombiBoiler: Model WT714R, WV714R
Connections from LWC3 Junction Box:
- Wiser Hub: L (Live), N (Neutral), 1 (COM), 2 (OFF), 3 (ON), 4 (SPARE).
- Programmer: LS (Live Supply), LR (Live Return).
- Boiler: L (Live), N (Neutral), E (Earth/Continuity), SWITCH (Call for Heat).
- Cyl. Thermostat: COM, CALL.
- Pump: (Refer to boiler handbook for pump overrun wiring).
Biflo system: Model WT724R, WV724R
Connections from LWC3 Junction Box:
- Wiser Hub: L (Live), N (Neutral), HW (Hot Water), CH (Heating).
- Programmer: LS (Live Supply), LR (Live Return).
- Motorised Valve (22mm 3 Port Mid Position Valve): L (Live), N (Neutral), 1 (Open), 2 (Closed), 3 (Switched Live).
Note: If there is an existing wired thermostat connected via the wallplate, you can: Disconnect it (remove thermostat wires from wallplate), OR Leave the thermostat connected providing it is ON and has no schedules that can interfere with Wiser, OR Turn the existing room stat up to max (creating a permanent supply through LIVE-IN and SWITCH-LIVE).
Twinzone system: Model WT724R, WV724R
Connections are similar to the Biflo system, typically involving connections for Heating and Hot Water.
3 Zone system: Model WT734R
Connections typically involve terminals for CH1, CH2, CH3, and mains supply.

Wiser Radiator Thermostat
For optimum comfort and savings, each radiator in your home should be fitted with a Wiser Radiator Thermostat. These can be purchased and installed individually.
Important: To limit temperature in other rooms, use existing thermostatic radiator heads. Regulate these according to manufacturer’s documentation for economy or comfort use.
Mounting Options
Wiser Radiator Thermostats come with two valve adaptors: M30x1.5mm and Danfoss RA. If neither works, consult the Valve Adaptor Guide on the Drayton website.
For Danfoss valve:
1. Remove the old thermostatic head from the valve body (water should not leak). Note: Turning the head to the highest position/number simplifies de-installation.
2. Slide the larger black plastic adaptor (small end first) over the valve. Ensure the grub screw hole faces away from you for correct orientation. Use a 2mm Allen key to tighten the grub screw.
3. Screw the Wiser Radiator Thermostat onto the adaptor until tight.
For Drayton valve (or similar):
1. Remove the old thermostatic head.
2. Place the small black plastic adaptor (serrated face down) onto the valve. Position the metal ring nut over the adaptor and screw it onto the valve.
3. Screw the Wiser Radiator Thermostat onto the adaptor until tight. If orientation is incorrect, slacken the ring nut, rotate the thermostat, and re-tighten.
Thermostatic Head Calibration: Upon fitting the relevant valve adaptor, twist the cap of the Radiator Thermostat in the `–` direction for 2 seconds until the right LED shows a solid blue.
Boost Function (Radiator Thermostat)
- Feeling a bit cool? Twist the cap in the `+` direction. The left LED will show a solid red for 5 seconds. This increases the setpoint by 2°C above ambient for 1 hour.
- Feeling a bit warm? Twist the cap in the `–` direction. The right LED will show a solid blue for 5 seconds. This closes the valve, stopping hot water flow to the radiator. This decreases the setpoint by 2°C below ambient for 1 hour.
Wiser Room Thermostat
Placement Recommendations:
- Place the Room Thermostat in a room heated most of the time (e.g., lounge/hallway).
- Place Radiator Thermostats in rooms not used all day (e.g., bedrooms).
- Rooms with Radiator Thermostats can be scheduled separately to avoid heating them with other rooms.
Boost Function (Room Thermostat)
1. Touch any button to wake the Room Thermostat.
2. Touch the centre button repeatedly to activate boost:
- 1st touch: 30 minutes
- 2nd touch: 1 hour
- 3rd touch: 2 hours
- 4th touch: 3 hours
- 5th touch: Cancel
The room will start to warm. A boost increases the setpoint by 2°C above ambient for the selected period. The setpoint can still be adjusted while boosted.
