Digimax 210
Programmable Thermostat
Compatible with Maxi Controller
User Guide
The RF DigiMax 210 thermostat does not need any extra
wiring and works within 30 meters range. It is equiped of a
secured RF code which the Maxi Controller will learn during
the installation process (see §8b). This code will assure that
the Maxi Controller will only answer to messages sent by
your DigiMax 210. This process is described at the end of
this manual.
1) To start :
Remove the battery insulation strip and check unit is func-
tioning.
2) Operation :
The DigiMax 210 Digital Room thermostat is simple to use.
The Liquid Crystal Display continuously shows ambient tem-
perature.

3) Installation :
Please read all installation instructions before proceeding.
The RF DigiMax 210 works with batteries. It does not need
any wire. If you wish it to replace an old cable thermostat,
isolate and secure the old wires, which are useless now. Do
not forget to cut the power when you take off the old thermo-
stat.

To change the “Set Point” (i.e. temperature requested), press
and hold the “SET” key and at the same time press “+” or “-”
to select the temperature setting. The display will show the
“Set Point” until the “SET” button is released. The display will
then show the ambient temperature.
When the DigiMax 210 instructs your heating system to switch
on, a small flame symbol appears at the bottom right of the
display.

1. Open the unit by slackening the retaining screw situated
in the bottom edge and hinging carefully upwards. Dis-
engage the unit from the wall-plate and place it to one
side for safe keeping. Take off the batteries.
6) Configuring
The unit is supplied with a 5°C minimum temperature set
point and configured as a heating thermostat as factory de-
faults. Two internal links can be used to reconfigure these
defaults.
3. Remove the battery insulation strip and check unit is func-
tioning, place it on its wall-plate
5) Fixing
1.The wall plate should be positionned with a minimum of
70 mm clearance all round to allow adequate air flow
2.Fix the wall-plate directly to a flat wall
The radio link does not mean that the wiring has been sim-
plified, but that the thermostat can be installed in any place of
your house to optimate your needs in heating.
We recommend you to make the installation with the Maxi
Controller before fixing your thermostat on the wall, in order
to be certain of its good operation at the selected place.
4) Position
The ideal position to locate the DigiMax 210 is about 1.5m
above floor level, accessible, free from extremes of tem-
perature and draught. Do not mount it on an outside wall,
above a radiator or where it may be subjected to direct sun-
light.

2. Locate and identify the two option Links 1 and 2. Use a
pair of small wire cutters to cut the appropriate links to
give the required configuration.
3. Cutting Link 1 will give a minimum temperature set point
of 16°C (factory default is 5°C) : in that case, the mini-
mum T° you can set is 16°C. Cut link 2 to display cooling
symbol instead of heating symbol.
4. Replace batteries being sure to observe the correct
polarities. Re-fit to plastic base and tighten retaining
screw. Check unit is functioning as required.

7) Battery replacement
A “flashing” battery low symbol will appear at the bottom left
of the display when the batteries start to approach the end of
their life. This indicates that they should be replaced within
the next month. Ultimately, the display will start flashing and
the thermostat will shut down until the batteries are replaced.
To replace the batteries, the following procedure should be
carried out.
1. Slacken the retaining screw on the unit and open by hing-
ing upwards the top edge.
2. Remove batteries and fit two new “AA” alkaline cells tak-
ing care to observe the correct battery polarities. Check
unit is functioning
3. Re-fit it to the plastic base and check that the RF link still
operates. This can be easily done by adjusting the re-
quested temperature under or over the level of the ambi-
ent temperature, in order to activate and disactivate sev-
eral times the boiler.

8) Connection to the the Maxi Controller
a) General operation
You can connect up to 4 DigiMax 210 to the Maxi Controller.
Depending on the information sent by the thermostats, the
Maxi Controller will send X10 messages on the power line
to turn On or Off X10 modules connected to your heaters or
boiler. These X10 modules can be Din appliance modules
(AD10) for boilers working on 230V or Universal modules
(UM7206) for boilers working on low voltage (up to 24V).
Each thermostat transmits the comfort setpoint and the am-
bient temperature. In the Maxi Controller you can enter a tem-
perature setback , between 1 and 9 degrees.
When the Maxi Controller is in “Disarm” or “Arm home” mode,
it will turn On or Off the X10 module connected to the boiler
depending of the ambient temperature and the comfort
setpoint.
When the console is in “Arm Away” mode, the setback differ-
ential to the comfort setpoint is applied. Suppose the ambi-
ent temperature is 15 °C, the comfort setpoint is 20°C, with a
setback of 4°C : the comfort setpoint minus the setback is
20°C - 4°C= 16°C, so the console will send an On message.
Suppose that now the ambient temperature is 19°C, the com-
fort setpoint minus the setback is 20°C - 4°C= 16°C, so the
console will send an OFF message.

b) Installation
1. Set the security console mode switch to the THERM posi-
tion.
2. To install a thermostat with the console, press and hold
its +and -keys together for 3 seconds. The DigiMax 210
will then transmit its unique digital code every 10 seconds
for the next 5 minutes. The display will show flash ‘]]]’
while this is happening.
3. After a few seconds you should hear a “bip” from the con-
sole and the first zone indicator should come on or, if you
have already intalled thermostats with the console, the
next available free zone will be indicated.
4. Go to the thermostat and press any key to stop the trans-
mission. The display will stop flashing ‘]]]’ and return to
normal.
5. Repeat this procedure for thermostat 2, 3 and 4. The first
thermostat will be installed on zone 1, the second will be
installed on zone 2...., the fourth on zone 4.
6. On the security console, reset the mode switch to Run1 or
Run2
Each thermostat will transmit a message every 5 minutes. If
during 20 minutes, the console does not receive any signal
from a thermostat, its RECORD LED will flash.
You can then put the slide switch to the THERM position to
see which zone (thermostat) has a problem.
The Maxi Controller transmits an X10 message on the unit
code of the zone allocated by the security console (see above)
and on the house code of the console + 1.
i.e. : If the console is on Housecode A,
- thermostat on zone 1 will generate message on code B1,
Page 8
- thermostat on zone 2 will generate message on code B2,
- thermostat on zone 3 will generate message on code B3,
- thermostat on zone 4 will generate message on code B4.
If the console is on Housecode B,
- thermostat on zone 1 will generate message on code C1,
thermostat on zone 2 message on code C2 etc...
c) programming of the setback temperature
1. Set the security console mode switch to the INSTALL po-
sition.
2. Key in your PIN code (factory default 0000).
3. Press key number 9
4. Press ENTER
5. Key in the setback temperature between 1 to 9 in degree
Celcius.
6. Press ENTER.
7. Reset the mode switch to Run1 or Run2
d) Telephone
When theMaxi Controller is “Arm Away”, it is possible using
its dial-in function features, to apply or not the setback differ-
ential to the “comfort” setpoint:
To apply the temperature set back
1. Call the security console from a touch tone or mobile
phone.
2. The console will answer your call with 3 short beeps.
3. After these beeps, enter your PIN code via the phone (fac-
tory default 0000).
4. The console confirms a correct PIN code with 3 short
beeps (an erratic PIN code is indicated by one long beep).
