Introduction

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

Step 1 Continued...

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. 6 x
1” (25mm) woodscrews, or on a flush mounting
single conduit box type UA1 (BS4662) using M3.5
x 14 bolts. Now fit the Wiser Heat Hub
w

allplate 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 Heat Hub
w

allplate and tighten the securing screws.

Check the 3A fuse, and switch on the mains.

Note: Ensure the Heat Hub
position with WiFi coverage.

Step 3: Testing the system

Heating and Hot Water buttons

Hot Water override button
(

WV724R , WT724R & WT734R only)

Pressing & holding the Hot Water button for >3s will
turn on the Hot Water for 1 hour. In this state the hot
water will be regulated by a cylinder thermostat or
the boiler. When the Hot Water override is active, the
Hot Water LED will flash green. To turn off the override
press the Hot Water button again. This will put the hot
water back under system control. Depending on the
system settings the hot water may stay on which will
be indicated by a solid green LED.

Tip: This feature can be used to ‘test’ an installation
prior to adding any devices.

Step 2b:
Wiring – boiler with
OpenTherm interface

If your boiler supports
OpenTherm, please follow the
instructions under this step.

6. Mount the Hub

The Wiser Heat HubR is an OpenTherm certified
product and will therefore operate with OpenTherm
certified boilers. Currently The Heat Hub
compatible with boilers that require a temperature

heating controls. For more information about wiring
options please consult the digital user guide found on

Connection Charts

Always switch off the mains before
removing the Wiser Heat Hub

!

Make the wiring connections, as shown in the
connection charts, for the appropriate system. For
surface wiring, snap out the cable entry strip on the
bottom edge of the wallplate. The Wiser Heat Hub
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 - a 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.
