Center EHE0200361 RF Programmable Room Thermostat Installation Guide
The Center EHE0200361 RF Programmable Room Thermostat is a modern wireless programmable thermostat that communicates with the relay box on an 868MHz Radio Frequency band to control a single heating system component, such as a boiler, pump, or zone valve. The thermostat includes a large LCD display with backlighting, making it easy to use during daily operation. The RF link between the individual room thermostat and the relay box in system packs is pre-configured at the factory and should be installed at the same site, making the installation process easy and fast.

and to see what other system options are available refer to section 4) Installer Mode.
1) Installing the Wireless System
1.1 Installing the Relay box
1.2 Installing the Room Thermostat
1.2.1 Power Up
STEP 1: Installing the Batteries:
a. Lift up the front cover of the thermostat to reveal the battery cover and product controls.
b. Remove the battery cover by pressing down and sliding out.
c. Insert the 2 x AA LR6 Alkaline Batteries supplied with the thermostat, ensuring the correct
orientation (see ‘Controls Layout’ in User Guide).
d. After a short pause the thermostat will display information on the screen and is now ready
for use.
e. Replace the battery cover by sliding it firmly back into the front of the thermostat.
1.2.2 RF Communication Check (Test Mode)
To check the RF communication, hold the room thermostat about 2-3 metres from the
installed relay box. Press the OFF button, then press the and buttons together with the
button for 3 seconds. The unit will display ‘TEST TRANSMIT’ and it will send test signals
to the relay box, flashing the green LED on every 6 seconds (relay output will remain off) for a
maximum of 10 minutes. When the green LED flashes on every 6 seconds proceed to the
next step.
NOTE: If the green LED is not switched at specified intervals, the red LED is flashing or if you
are installing a replacement relay box or room thermostat, follow the procedures described in
section 4.1 Binding / Rebinding Procedure.
STEP 2: Setting the Time
To set the Date and Time:
a. Press the DAY button once and the ‘day indicator’ will begin to flash.
b. Press the DAY button until the correct day is reached (Day 1 = Monday). Press the
button to confirm.
c. Press either of the or buttons once to enter time setting mode. The LCD screen
flashes the time digits (when the unit is powered for the first time the display shows 12:00).
d. Use the or buttons to set the correct time then press the button to confirm.
Each press of the buttons will change the time by one minute and holding them down will
change the time slowly at first and get progressively quicker.
Note: If this mode is entered accidentally then press the AUTO, MAN or OFF buttons to exit.

Note: If this mode is entered accidentally then press the AUTO, MAN or OFF buttons to exit.
1.2.3 Locating the Room Thermostat
While still in the Test Mode, as described in section 1.2.2, the room thermostat should be
located taking the following into consideration and reviewing the illustrations below:
1. Find a suitable location where the signal transmission is reliable. Reliable transmission is
indicated when the relay box is flashing the green LED every 6 seconds. NOTE: The relay
box relay will be off.
2. Install the room thermostat on the wall using the wall bracket as shown in the diagram
below.
3. Exit the Test Mode by pressing the AUTO or OFF button.
2.1 Automatic Operation
The relay box receives the heat demand
(0-100%) signal from the room thermostat.
The room thermostat will display the symbol
on the LCD display whenever more heat is
required. Depending on the demand the relay
box will switch the heating device on to match
the current requirements of the system.
The green LED indicates the status of the relay
output:
• Green LED on = relay on
• Green LED off = relay off
Installer Mode is used to alter the system settings for specific applications, to use the special
features of the room thermostat in a different way or to alter the factory preset parameters.
Parameters are divided into two groups:
- Category 1 parameters – Room Thermostat Setup
- Category 2 parameters – System Setup.
These are all listed in section 3.4 Installer Parameters Table.
2.2 Temporary Manual Override
Pressing the relay box button will override the current relay position. As soon as
the next signal is received from the room thermostat the relay box will return back
to automatic operation as the automatic control has higher priority than manual
operation.
2.3 Communications Loss
If the RF communication is lost for a period of 1 hour the red LED will illuminate to
indicate that no RF messages have been received during the last hour.
The relay box will also enter the failsafe mode as selected in Installer Mode
(see section 3.2 Relay box Fail-Safe Mode Setup). To allow manual control
of the relay box output manual override is available in fail-safe mode. When RF
communication is restored the relay box will automatically return to normal operation.
You can now use the USER GUIDE supplied with the room thermostat to
demonstrate how it works to the home owner.
1.3 System Check
Now a simple test can be completed to check the full system has been installed correctly:
1. Press the OFF button.
2. Check the boiler supply is on and check that the green LED on the relay box is off.
3. Press the MAN button.
4. Adjust the setpoint up to the maximum (35°C) by pressing the button. The boiler
should come on (green LED ON on relay box) after a few seconds and the symbol
appears on the room thermostat LCD display.
5. Press the OFF button. The boiler will go off (green LED OFF on relay box) after a few
seconds and the symbol disappears.
6. Check the system operation by alternately pressing the MAN and OFF buttons several
times, bearing in mind the switching delay referred to above.
Now, you should have completed the installation successfully - to begin operating at the
default factory settings press the AUTO button or press PROG to modify the built-in heating
program accordingly.
Wall bracket
• The room thermostat should be installed in an open space for best
performance as it is a radio frequency device.
• Leave at least 30cm distance from any metal objects including wall boxes and at least 1 metre from any other
electrical equipment eg. radio, TV, PC etc.
• Do not mount onto metal wall boxes.
• It is recommended that the relay box is fully installed.

3.3 Using the Room Thermostat for Specific Applications
The RF room thermostat is a versatile controller that can be used to control many different
applications. For most typical applications, like wall-hung gas fired combination boiler control
or zone valve control, no adjustments from the factory settings are required. For other
applications, like controlling an oil burner, the best system performance can be achieved by
modifying selected parameters of the room thermostat in the Installer mode. The table below
lists the most common settings used for specific applications.

3.2 Relay box Fail-Safe Mode Setup
The failsafe mode defines the relay box output relay status if the RF communication is lost
(e.g. when the room thermostat stops communicating due to discharged batteries). The
factory setting keeps the relay permanently off when communications is lost. If this factory
setting needs to be changed follow the instructions below:
1. Enter Installer mode as described above.
2. Press the button to enter category 2 parameters.
3. Select the parameter 7:LC by pressing the button.
4. Select the fail-safe mode by pressing or buttons:
• 0 - when RF communication is lost the relay will be held in OFF position.
• 1 - when RF communication is lost the relay output will cycle at 20% on 80% off.
5. Press the button to accept the change.
6. Attach appropriate label to the relay box to indicate the selected fail-safe mode.
IMPORTANT: To enable the frost protection when RF communication is lost, select the fail-safe
mode 1. For systems with separate frost protection thermostat or where frost protection is not
required select fail-safe mode 0.

Frequently asked questions
To bind or rebind the thermostat and relay box, follow the steps outlined in section 4.1 Binding / Rebinding Procedure in the Installation Guide.
Communication loss can be caused by several factors, including incorrect placement of the thermostat, interference from other electrical devices, or depleted batteries. Refer to the troubleshooting guide in section 5.1 of the Installation Guide for possible solutions.
If the relay box does not respond to setpoint changes, you may need to bind the thermostat and relay box. Reset the relay box and follow the binding procedure as described in section 4.1 of the Installation Guide.
The green LED on the relay box indicates the status of the relay output. A green LED indicates that the relay is on, and a green LED off indicates that the relay is off.
