Drayton Wiser Smart Thermostat and Multi Zone Kit Installation Guide

Drayton Wiser Smart Thermostat and Multi Zone Kit

Introduction

Welcome!

Save this guide for future reference.

If you are replacing an existing controller/programmer and don’t need to make any wiring changes that’s great news. All you need to do is remove the old product and fit your new Wiser Hub® to the existing wallplate.
If you are fitting a new system or require re-wiring please contact an installer.

IMPORTANT

• Do not attempt to install this product if you are not familiar with how to install mains-powered electrical appliances.
• Always switch off the mains before removing controller and never fit it to a live wallplate.

Mounting the wallplate

Step 1: Mounting the wallplate

Option 1: Fitting a new wall plate

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 HubR onto the wallplate and tighten the securing screws. Check the 3A fuse, and switch on the mains.

Option 2: Using an existing industry standard wall plate

Loosen the securing screws on the old controller/ programmer and unplug it. Check that there is 70mm clearance to the right of the wall plate and 25mm above it. Check the wiring diagram for your product model to compare terminals and, if necessary, change the wiring of the wall plate to suit. Now fit the Wiser HubR onto the wall plate and tighten the securing screws. Check the 3A fuse, and switch on the mains.

Warning

• 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.

Wiring

Step 2a: Wiring – wallplate

Make sure mains input has a 3 amp fuse.
CAUTION:  Before installation, make sure the mains supply is switched off!

• One channel only: Note that the output contacts are voltage-free*, so power needs to be put on 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.
• Three channel only: Make a note of which circuit is connected to CH 1 and CH3 respectively as this information is needed later, during commissioning, when room thermostats are added to the system.

Note: If there is an existing wired thermostat connected via the wall plate, 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 HubR onto the wall plate and tighten the securing screws. Check the 3A fuse and switch on the mains.

Step 2b: Wiring- boiler with Communication module interface

If your boiler supports Communication module, please follow the instructions under this step

Existing Communication module installation

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

Note

• communication module works only with Wiser Kit 1 systems (heating only).
• The communication module will not work on systems with a separate hot water cylinder (Kits 2 and 3) even if the communication module is present.

Testing the system

Step 3: Testing the system

Connection Charts

Warning: Always switch off the mains before removing the Wiser HubR – and never fit it to a live wallplate!

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 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, 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.

  • LS – Live Supply
  • LR = Live Return

Wiser Room Thermostat

Thermostat Kits 1, 2 & 3:

For room thermostat only systems the positioning is important as this will control the boiler to your entire home. In these systems 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.

Boost

Feeling a bit cool?

1. Go to the Room Thermostat and touch any button to wake it up.
2. Touch the centre button again to activate boost 1st touch = 30 minutes,
   • 2nd touch = 1 hour
   • 3rd touch= 2 hours,
   • 4th touch= 3 hours
   • 5th touch= Cancel
3. Shortly after the room will start to warm.

Note

• A boost will increase the setpoint to 2’C above the ambient temperature for the time period selected. You can still adjust the setpoint when boosted.

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 shou Id 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 .Smm 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.

Fitting M30x1.5mm

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.

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 fitting of the relevant valve adaptor, twist the cap a/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

Boost
