Drayton P710R Programmable Room Thermostat Instruction Manual

Drayton P710R Programmable Room Thermostat 

Applications

The electronic room thermostat MiStat P can be used for temperature control together with:

• Boilers
• Oil and gas warm water heating
• Actuators of fl oor heating systems or radiators
• Circulating pumps
• Heat pumps

A MiStat R receiver is required for operation.
Note: To ensure a properly working heating system, the menu items in the Installer settings have to be set according to the needs of the heating system, see step 5.

Caution!
The radio receiver may be installed only by a competent electrician in compliance with the circuit diagram enclosed in the top housing cover or in compliance with these instructions. The current safety regulations must be observed.
In order to achieve protection class II, adequate installation measures must be taken.
This radio receiver, which can be installed separately, is designed exclusively for temperature control in dry and closed rooms and standard environments. This electronic device was created according EN60730-1, it operates according working principle 1C.

Instructions

Step 1: Mounting the Wall-plate

IMPORTANT:
Installation must only be carried out by a qualifi ed electrician or heating engineer. Make sure mains input has a 3 amp fuse.
CAUTION! Before installation, make sure the mains supply is switched off!

Option 1: Fitting a new wall-plate
The ideal location is close to the boiler or central heating system. For the best performance install in an open space, at least 30cm distance from any metal objects including wall boxes and the boiler housing. It is recommended that the MiStat R is mounted on the wall nearest the fi nal location of the MiStat P room unit and not less than 30cm from the boiler side panel.
Loosen the securing screws, remove the wallplate and, if surface wiring is to be used, snap out
the cable entry strip on the bottom edge of the wallplate with a pair of pliers. Fix the wallplate, terminals at the top, either direct onto the fl at wall using wall plugs and no 6 x1” wood screws or on a plastic fl ush mounting single conduit box using M3.5 x 14 screws. Check that there’s 20mm clearance to the right of the wall-plate and 25mm above it. Complete the wiring to the MiStat R wallplate in accordance with the wiring diagram in step 2, to comply with current IEE regulations. Place the MiStat R onto the wallplate and tighten the securing screws.
Check the 3A fuse, and switch on the mains.
Warning: Installing the MiStat R too close to the metal side panel or mains cables may interfere with the radio signal.

Option 2: Using an existing wall-plate
Loosen the securing screws on the old receiver and unplug it. Check that there’s 20mm 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 plug the MiStat R unit into the
wall-plate and tighten the securing screws.
Check the 3A fuse, and switch on the mains.

Step 2: Wiring

This product is double insulated and does not require an earth connection. The MiStat R should be wired to the boiler or central heating wiring using the correct type of cable or fl ex. The MiStat R should be wired to replace hard wired room
or programmable thermostats, as shown on the system or boiler wiring diagrams.
Always check other manufacturers instructions for compatibility.

Step 3: Signal Strength

The MiStat Programmable Room thermostat is pre-bound to the MiStat receiver in the factory so they just need to be positioned in the best place for wireless communication.
To help with this there is a built in Signal strength indicator as shown below (see also Step 5 Installer settings).
It is recommended that the signal strength is ‘Good’ or ‘Very Good’ to ensure ongoing communication is maintained.

If ‘Poor’ is displayed, look for a better location.
If ‘No Signal’ is displayed, try connecting again with the room unit in a different position.
Note: If not bound, the bind screen will be visible. For commissioning see Step 6

Step 4: Mounting Options

Once the best position has been identified, the MiStat should be fixed to the wall using the wall bracket as shown.

Care should be taken to mount the thermostat in a position which is not subject to direct sunlight or draughts. Preferably it should be mounted on an inside wall about 1.2m (4ft) above the fl oor in a position where it can respond to room temperature but away from the direct infl uence of radiators or other appliances giving off heat.

NB. MiStat can also be positioned using the table stand included.

It has to be placed in a location where it will be able to control the room temperature.

Step 5: Installer Settings

Customise the controller according to application requirements (from installer only)

• From the Home screen, select Settings, then Installer settings as shown.
• From here you can edit the assigned zones, rename them if required and adjust the Service settings.
• If using the Service feature, remember to set the Password when complete.

Step 6: Commissioning

Note: Only needed if not already bound, ie if replacing either the MiStat thermostat or the MiStat receiver.

1. Turn on power for the receiver. The red LED will come on.
   If LED is green or Off, the device is already bound, no further action needed here (If a separate programmer/Timer is fi tted, ensure that it is switched on)
2. Push the button for >5 Seconds and the LED will fl ash red – yellow – green — -red – yellow -green…
3. Enter binding mode on the corresponding MiStat room unit, see Step 5: Installer settings Important: It is essential, that the binding is carried out between the corresponding room unit and the receiver
4. The possible results are as follows;
   1. ‘° Bind OK’ will be indicated on the MiStat room unit if binding was successful.
      After a few seconds the Signal strength will be indicated on both the MiStat room unit and the MiStat receiver, see below.
   2. ‘X˛ Bind Failed’ will be displayed if unsuccessful.
   3. If ‘Poor’ signal is displayed, look for a better location.
   4. If ‘No Signal’ is displayed, try connecting again with the room unit in a different position.

Immediately after binding, these signals will indicate the signal quality for 1 minute.

• three green fl ashes = Very good signal
• double amber fl ashes = Good signal
• single red fl ashes = Poor signal
• steady red = No signal

To check the wireless connection
A green LED on the receiver will indicate a good RF connection.
