Wiser Underfloor Heating Controller

Ca ution!
This device should be installed by a qualified and competent electrician according to the wiring diagram on the product or in this installer guide. Current safety measures  should be observed. To achieve the demands of Protection Class II the relevant installation requirements should be applied.
This electronic device is used for controlling thermostats and valves in dry and closed spaces

The following items are needed to install a Wiser Underfloor Heating system:

• Wiser Underfloor Heating Controllers
• Wiser HubR
• Wiser Room Thermostat
• Wiser Radiator Thermostat (optionally for mixed system)
• A smartphone with the installed Wiser Home app
  NOTE: The system can be installed without connecting to a wi-fi router, see Point 1g

a) Application (intended use)
The Wiser UFH Controller should only be used with hydronic UFH systems. The device is a part of the Wiser control system. It works in conjunction with the Wiser Hub R and Wiser Room Thermostats, and it controls the temperature in individual rooms/zones.
With mixed systems (UFH and radiators) Wiser Radiator Thermostats can be added and in this way a complete hydronic heating system can be controlled. The system is  simple to expand:
2 further Wiser UFH Controller (and optionally Wiser Radiator Thermostats) can be added.

• 1x UFH max. 6 zones
• 2x UFH max. 12 zones
• 3x UFH max. 16 zones

b) Wiser UFH Controller features

• 230V terminals to power the thermal actuators
• 6 channels/zones (each controlled by a Wiser Room Thermostat)
• Up to 14 normally-closed 230V thermal actuators
• Fuse to protect against any short circuits when connecting the thermal actuators
• Overload protection against switching all thermal actuators simultaneously (channels are switched one after the other with a delay)
• Pump protection (if the heating is not used for one week the pump will run briefly).

c) Wiser system features

• Individual control of up to 16 rooms/zones when using 3 Wiser UFH Controllers
• Control of mixed hydronic heating systems (radiators and UFH)
• Individual temperature schedule for each room/zone
• Manual and away modes
• Cloud features such as Eco Mode, Geofencing through IFTTT and voice activation with Amazon Alexa and the Google Assistant from anywhere in the world.
  As the Wiser system is constantly being upgraded please look for further features on the Wiser website wiser.draytoncontrols.co.uk.

d) Installation
The Wiser UFH Controller is installed using the supplied DIN-Rail. It can be clipped on and off using the green clips on the rear.
To remove
Push the green clip downwards using a screwdriver until it clicks
To attached
With a screwdriver push the green clip upwards until it clicks

e) Electrical connection
The system can be tested with or without the app.
Attention: before installation isolate from mains

Open the cover:
Insert a screwdriver and push the cover to the left according to the symbols on the cover.
The wiring diagram is shown on the device.
Wiring must be carried out by a qualified and competent electrician
The UFH Controller is only for fixed wiring For optimum cable retention remove 9mm of cable insulation
Only use cables of the specification below All cables must be fully inserted in the connector blocks After wiring please ensure that the cables are:
− correctly connected
− fully inserted
− firmly in position
− not twisted or under tension

Close the cover:
Press the cover on the rear housing and then push to the right until it clicks.

Minimum cable characteristics:
Thermal actuators and mains supply: 0.75mm , 2-core, flat
Remote sensor: 0.25mm 2 , 1-core (x2),
Round Dew sensor: 0.25mm 2 2 , 1-core (x2), round
Heating / cooling, pump and boiler: 0.75mm 2 , 2-core, round

NOTE: in larger rooms several UFH zones can be associated with a room thermostat. For example by connecting Channels 1 and 2 up to 8 thermal actuators can be used in  one room.

1. Thermal Actuator relays
   Thermal actuators are connected to each zone. Polarity is not important.

2. Power consumption
   To supply the UFH Controller please connect as follows: 230Vac.
   Internal 3.15A fuse

3. Pump contact
   Connect as indicated below:
   NOTE: The pump is activated when any valve is closed. The pump will run for 2 minutes after the last valve closes.

4. Boiler contact
   The boiler will be switched off when all valves are closed. The relay is normally open and can be used volt-free (directly to the boiler) or switched live with 230Vac (to a  zone valve).
   Attention: May still be live even if mains is switched off.
   When several (max 3) Wiser UFH Controllers are used, please connect as per the diagram on the right.

5. Heating/Cooling input
   The system will switch to cooling mode when 230V is applied.
   Note: when several (max 3) controllers are used only one heating/cooling input is required. The complete system will change to cooling mode.

In the Wiser Home app rooms can be excluded from cooling if required (eg bathrooms).
Note also that only rooms with UFH will cool when using cooling mode.

6. Dew sensor and remote sensor inputs
The following sensors should be connected:
Drayton dew sensor 193683
When in cooling mode the dew sensor can detect condensation and turn off the cooling. It can be attached to the manifold.
Drayton remote sensor 193720
The remote floor sensor can be used as a high or low limit to protect the floor. It works on one zone only.

f) External antenna
The supplied antenna must be used to ensure consistent communication with Wiser devices. The antenna is screwed to the connector underneath the Wiser UFH Controller.
To optimise signal strength the antenna should be mounted in a suitable position outside and away from the manifold cabinet (not on the metal frame of the manifold  cabinet).
Use of supplied antenna with a third-party extension cable:
In many applications an extension cable can be used to optimise the mounting position of the antenna. Please note that in this case the extension cable may reduce the signal,  i.e. the signal range may be reduced (see table below).

Wiser Room Thermostats

Intended use
The Wiser Room Thermostat measures the temperature in the room.
The HubR controls room temperature using this information.
NOTE: every room with a UFH channel must have an associated  room thermostat.
A room thermostat also displays the current room temperature, the set temperature and the humidity level. The set temperature can be adjusted and a boost set.
The room thermostat receives the set temperature from the HubR and this can be changed in the app. It follows the selected operation (automatic, manual, away, boost).  These can be overridden here (in auto mode only until the next period).

Adding Wiser Radiator Thermostats

Wiser can be installed and used without internet access:
On the app select “set up new system” but skip the last step “Now we will connect the Wiser HubR to your Wi-Fi router”.

Wiser can also control missed systems.
Applications:
Some rooms are heated by radiators and others by underfloor heating In the same room there may be underfloor heating and a radiator.
In this case the room will need two room names, one for the radiator and the other for UFH, for example:
Lounge UFH
Lounge Radiator
Follow the instructions in the app to add rooms.

Settings, then select Devices, then +

Removing devices from the system

Devices can be removed in various ways:
Using by the app: open the settings menu the Devices. Search for the relevant device, press >, then “Remove from system”. This is the recommended way to remove devices.
Note: if a removed device has no connection (e.g. dead batteries) then it must also be removed on the device itself, see below:
On the Room Thermostat: replace the dead batteries with new ones. When the green start screen is displayed press and hold the and buttons for 20 seconds until the screen  “Join a network” appears. The Room Thermostat has now been removed from the system and can be added again.
On the Radiator Thermostat: turn the cap to for >15 seconds until the red LED light flashes 8 times. When the cap is released all LEDs will flash. The valve will then open, the left and right LEDs will flash, and finally the middle LED will be solid amber (for 5 minutes).
On the Wiser Hub R for >20 seconds until all LEDs flash. The setup LED : press and hold the setup button will be amber.
Reset the Hub R : press the button for >20 seconds until the LED goes out and then goes amber followed by red. Release the button when the LED is red and it will shortly turn green. At this point the device is ready for pairing
