Radio system set-up
The chronostat turns-on or turns-off a relay in the receiving unit (receiver) by a radio link.
Before installing the chronostat in the desired position, it is necessary to test if the
receiving unit correctly receives its radio signals. To do this the chronostat must be
turned-on in the “Test” mode. The operation is described in the following.
Open the thermostat box removing the plastic back, use a small screwdriver, place it
between the back panel and the chronostat’s body as shown in (9) Fig. 10 then apply a
slight pressure. In Fig. 11 is visible the appliance’s internal layout. Set the appropriate
address in the dip-switches (11), the address is split in two parts, “family” and “device”.
The family address must match the family address set in the receiver unit, the device
address must match one device address of one output channel of the receiver. Take
into account that different thermostats used with the same receiving unit must operate
with different device addresses to avoid data collision and malfunction. See receiver’s
documentation for further explanations.
If you are using a one-channel receiver, the address can be set randomly, but attention
must be paid if more than one wireless thermostat are installed in the same building or in
the close area, the address must be different.
Turn-on the receiving unit and position it close to the desired final place.
In the chronostat push down the microswitch N.1, it is located in the group of the
additional functions microswitch in the back side (8) Fig. 10, this enables the “Test
mode” operation. Make sure that the batteries are correctly inserted, do not use old or
non-alkaline batteries. Now the chronostat is operanting in ‘Test’ mode it continuously
transmits On and Off signals to the receiver every about 3 seconds.
In the receiving unit the relevant relay output should continuously toggle between On and
Off state, every 3 seconds. This output state in the receiver is also displayed by its led. If
this happens the chronostat is correctly communicating with the receiver.
When positioning the chronostat in the desired room, ensure that they still communicate
well, checking the relevant output which should be continuously toggled.
If the thermostat is placed too far from the receiver, the relevant relay output will not
toggle and remain stuck in the On or Off state. In this case the chronostat should be
positioned in another place, closer to the receiver or as far as possible from metal sheets
or reinforced cement walls which could weaken the radio signals.
The signal power can be monitored in the receiver unit, please see the receiver instruction
for more information.
Once the optimal position is found, push up the microswitch N.1, (8) Fig. 10 to stop the
test and to enable the normal operation.
Note that in the normal operation the relay status in the receiver will be updated every
about 3 minutes, so it is normal not to get an immediate response when changing the
Comfort or Economy temperature setpoint, by moving the relevant knobs.
Close the chronostat by placing the plastic back and pushing it.
Proceed with the mechanical installation.
