Option 1: Fitting a new 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.
Position with 70mm clearance to the right, 25mm above and sufficient room to access the securing screws underneath. Fix, with terminals at the top, either direct to a flat wall using wall plugs and No. 6x 1” (25mm) woodscrews, or ona flush mounting single conduit box type UA1 (BS4662) using M3.5 x 14 bolts. Now fit the Wiser Hub® onto the wallplate and
tighten the securing screws. Check the 3A fuse, and switch on the mains.

Option 2: Using an existing industry standard wallplate

Loosen the securing screws on the old controller/ programmer and unplug it. Check that there is 70mm clearance to the right of the wallplate and 25mm above it. Check the wiring diagram for your product model to compare terminals and if necessary, change the wiring of the wallplate to suit. Now fit the Wiser Hub® onto the wallplate and tighten the 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 Hub” 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!

DO NOT use a surface mounting box as the wallplate is not designed for this purpose.

Note: If there is an existing wired thermostat connected via the
wallplate, you can:

– Disconnect it i.e. remove the thermostat wires from the wallplate, or
– Leave the thermostat connected providing it is ON and there are
no schedules that can interfere with Wiser, or
– Turn the existing room stat up to max. This is the same as creating a
permanent supply through the LIVE-IN and SWITCH-LIVE

Note: After wiring, fit the Wiser Hub® onto the wallplate and tighten the securing screws. Check the 3A fuse and switch on the mains.

Step 2b: Wiring ­ boiler with OpenTherm interface

If your boiler supports Open Term, please follow the instructions under this step.
Existing Open Term installation

1. Remove the OpenTherm cables from the existing controller of thermostat.
2. Remove the OpenTherm module from the rear of the Wiser Hub®.
3. Wire in the OpenTherm cables into the OpenTherm module. It does not matter which way the cables are wired.
4. Replace the OpenTherm module into the Hub®.
5. Wire L & N on the wallplate from a separate supply with a 3A fuse.
6. Mount the Hub® on the wallplate.

The Wiser Hub® is an OpenTherm certified product and will
therefore operate with OpenTherm certified boilers. Currently
The Hub® is not compatible with boilers that require a
temperature for domestic hot water to be provided by the
external heating controls. For more information about wiring
options please consult the digital user guide found on
wiser.draytoncontrols.co.uk/support
Heating override button ~

Pressing & holding the Heating button for >3s will turn on
the heating for 2 hours. In this state the boiler will self-
regulate its temperature. When the Heating override is
active, the Heating LED will flash green. To turn off the
override press the Heating button again. This will put the
heating back under system control. Depending on the
system settings the heating may stay on which will be
indicated by a solid green LED.

A ‘Always switch off the mains before

Make the wiring connections, as shown in the connection
charts, forthe appropriate system. For surface wiring, snap
out the cable entry strip on the bottom edge of the wallplate.
The Wiser Hub® 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, i.e. remove the thermostat wires
from the wiring centre – @ link must be inserted between the
terminals where the thermostat common and call for heat
wires are located in the wiring centre.

Arrowed numbers relate to the junction box.
*Consult boiler handbook for details of pump overrun wiring.
After wiring, clip on the unit and tighten the securing screws.
Check the mains input has a 3A fuse, and. switch on the mains

Wiser Room Thermostat

Thermostat Kits 1,2 &

For room thermostat only systems the positioning is
important as this will control the boiler to your entire
home. In these systerns mechanical TRVs should be used
as a minimum to provide a level of room heating control

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.

Wiser Radiator Thermostat

Multi-zone System:

Economy use:

® Place the Room Thermostat in a room which is heated most of
the time, typically the lounge/hallway.

© Place the Radiator Thermostat(s) in rooms that are not used all
day such as bedrooms.

The room with Radiator Thermostats can now be scheduled
separately to avoid heating them with the rest of the rooms.

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.

Mounting Options

As radiator valve bodies are not all the same, Wiser Radiator
Thermostats come with two valve adaptors; M30x1.5mm and
Danfoss RA (If however, neither work with your radiator valves,
consult the Valve Adaptor Guide on the Drayton website).

First remove the old thermostatic head from the valve body. Water
should not leak from the valve whilst doing this. (Refer to the
manufacturer’s instructions if needed.) You are now ready to install
your new Wiser Radiator Thermostat.

Note: Turning the head to the highest position/number will simplify de- installation

Once you have set up your Radiator Thermostat(s) through the app,
you will be asked to select and fit the required adaptor. When fitting
and tightening the adaptor to the Radiator Thermostat, please make
sure that the O-ring is firmly seated above the thread as to avoid
damaging the O-ring. Tighten by hand only.

Place the small black plastic adaptor serrated face down onto
the valve. Position the metal ring nut over the black plastic
adaptor and screw it onto the valve. Now screw the Radiator
Thermostat onto the black plastic adaptor until tight. If the
Radiator Thermostat is not facing the right direction, slacken
the metal ring nut and rotate the Radiator Thermostat as
required and re-tighten the metal ring nut.

Thermostatic head calibration
Upon fitting of 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.

Wiser Radiator Thermostat

Slide the larger black plastic adaptor small end first over the valve.
Make sure that the hole containing the grub screw is facing away
from you. This way, once its mounted, the markings of the Radiator
Thermostat will be in the required position. Use a 2mm size Allen
key to tighten the grub screw. Now screw the Radiator Thermostat
onto the larger black plastic adaptor until tight.

Thermostatic head calibration

Upon fiting of the relevant valve adaptor, twist the cap of Radiator
Thermostat in the – direction for 2 seconds until the right LED
shows a solid blue.

IMPORTANT:

To limit temperature in other rooms
use existing thermostatic radiator
heads. We suggest regulating these
according to manufacturer’s
documentation to provide either
economy or comfort use
