Center 340009 RF Thermostat

Introduction

340009 is an RF thermostat. The Room Unit communicates with the relay Box on an 868MHz Radio Frequency (RF) to control a single heating system components such as a boiler, pump or zone valve. Neither product will communicate with other RF products that use different frequencies or communication protocols.
Note: The RF link between the Room Unit and Relay Box is pre-configured at the factory so these units should be installed together at the same site. If the units become separated or one of them needs to be replaced, they will need to be bound together – see Binding or Re-Binding Procedure.

Specification

Installing the Relay Box

1. The Relay Box is an RF device. For the best performance install in an open space. Leave at least 30cm distance from any metal objects including wall boxes and boiler housing.
   Do not mount on metal wall boxes.
   EMC compliance considerations Keep AC mains supply/load cables separate from signal wiring.
2. NOTE: The Relay Box contains no user-serviceable parts. It should be opened and installed by a qualified installer only.
   WARNING: Electrostatic sensitive device! Do not touch the circuit board.

 

Testing the Thermostat RF Connection

1. Apply mains electrical power to the Relay Box
2. Power up the Room Unit
   • Remove the cover
   • Remove and discard the plastic tab inside the battery compartment, illuminating the display
3. Hold the Room Unit 2-3 metres from the Relay Box
4. Put the Room Unit into TEST Mode
   • Press and hold the button for 2 seconds
   • Press and hold the and buttons together until the screen changes as shown
   • Press thebutton once
   • Press and hold thebutton until the screen displays tEst. If the green light on the Relay Box does not flash periodically, the units are not Bound together. See Binding or Re-Binding Procedure to re-establish wireless communication
   • Next test the signal strength to find
   • Suitable location for the Room Unit installation
     Testing the RF Signal Strength
5. While still in TEST mode:
   • Press and hold the button to enter   SIGNAL STRENGTH Mode
   • The display will show SS and a number from 0 to 5 indicating signal strength. This number will reset to zero every few seconds as a new signal measurement is made
   • Strength 0, 1, 2 = POOR SIGNAL => move Room Unit to a better location Strength 3, 4, 5 = GOOD SIGNAL => ok to install Room Unit in this location
6. Press and hold the button to end the test

Installing the Room Unit

Install where signal strength is good, at least 30cm from any metal objects and at least
1m away from other electrical devices. Avoid proximity to heat sources or draughts.

Cr	Boiler cycles per hour	6 cycles per hour	3, 6, 9, 12 cycles
Pb	Proportional Band Width	1.5°C	1.5 to 3.0°C
tO	Temperature Offset	0 = no offset	+3 to -3°C
uL	Maximum set temperature limit	35°C	21 to 35°C
LL	Minimum set temperature limit	5°C	5 to 21°C
HC	Heating/ Cooling changeover enable	0 = no changeover	1 = changeover allowed*
OS	Frost Protection temperature	5°C	5 to 16°C
LC	Loss of Communications instruction	0 = switch off	0 or 1 = operate 20% on
FS	RESET to factory defaults	0 = no change	1 = restore factory settings

* To change from Heating to Cooling Mode, press and  hold both and buttons together for 3 seconds

Binding or Re-Binding Procedure

Only Bind or Re-Bind if the units become separated or one of them needs replaced.
No need to re-connect after power cuts or battery replacement.

1. Put the Relay Box into Binding Mode
   • Press and hold the Relay Box button for 15 seconds to cancel any prior Binding information
   • After releasing the button, hold it down again for 5 seconds until the red light flashes evenly

   • Press the button so the screen displays COnt
   • Press thebutton repeatedly until the screen displays CLr. Then press to clear any previous binding to other devices
   • Press the button again to return to Binding Mode, where the screen displays COnt
3. Press the button to send the Binding signal to the Relay Box. If successful, the red light on the Relay Box will stop flashing and turn off.
