REGULATION WITH DEAD BAND
The receiver can be set on jumper JP1 to regulate with dead band
(see step 7 under "Installation").
When regulating with dead band, the receiver drives the “heat”
valve with the relay of channel 1 and the “cool” valve with the
relay of channel 2.

When regulating with dead band, the receiver can learn only one
thermostat on channel 1 and the thermostat will drive both relays
of channel 1 and channel 2. If the setpoint temperature is greater
than the room temperature there is a “heating” request and the
“heat” valve on relay 1 will be turned on, conversely, if the
setpoint temperature is lower than the room temperature there is
a “cooling” request and the “cool” valve on relay 2 will be turned
on. If the room temperature matches the setpoint temperature
both outputs remain off. More in detail the width of the dead band
determines the temperature range in which the outputs remain
off. The dead band‘s width can be set on the trimmer with a small
screwdriver in the range 1 to 11 °C (see step 8 in "Installation").
The heating output will be activated when the room temperature
is below the setpoint temperature of half the dead band, while the
cool output will be activated when the room temperature will be
higher than the temperature setpoint of half the dead band.
When in dead band regulation it is assumed that the heating and
cooling systems are always available and the heating/cooling
status of the transmitter will be ignored, as it is the room
temperature that will determine whether to heat or to cool.
When in dead band regulation, the “test” mode of the thermostat
will toggle every 2 seconds only output 1 (heating).

SYMPTOM:

PROBABLE CAUSE: The channels in question are in an “alarm

communication.
When the receiver is set for dead band regulation, it can not

The consumer is guaranteed against any lack of conformity
according to the European Directive 1999/44/EC as well as to the
manufacturer’s document about the warranty policy. The full text
of warranty is available on request from the seller.
SYMPTOM:
The receiver’s LED remain red despite the
communication with the transmitter had
been restored.
PROBABLE CAUSE: The long-term analysis of the signal quality
reports the history of the last 90 minutes of
the channel activity.
REMEDY:
Verify with the “test” mode that the
“immediate” indication on the LED indicates
a sufficient signal quality and allow up to
90 minutes for the long-term analysis to
turn green.
