G) INTERNAL RELAYS CONTROL :
The internal relays CONTACTS are enabled to change states only
ONCE every 30 SECONDS
.
The contact designated as “
COOL
” will be
energized
when a demand for cooling (Air-Conditioning) is detected.
The contact designated as “
HEAT
” will be
energized
when a demand for heating is detected.
Both relays contacts are completely isolated from each other and from all other circuits.
STEADY
Light in the upper-left corner of the display indicates that the “
HEAT”
relay is energized.
BLINKING
Light in the upper-left corner of the display indicates that the “
COOL”
relay is energized.
These lights may be active
ONLY
when the temperature is on the display.
To DISABLE the PROGRAMMABLE THERMOSTAT operation:
Disable the function
Fn 52
. (see FUNCTION SETUP Procedure section in the Manual ). All previously preset events data
will be retained in the memory unaffected.
USEFUL TIP
During the Normal Operation, when the thermostat is set to operate in the AUTO or MANU mode, it is possible to find out
which event is currently being executed and with what presets.
To do that press the
SET
key on the remote at any time. The most recently executed event will be displayed. Use the
NXT
key to scroll through the day, temperature and hrs:minutes for that event.
NOTE that at this point the system will also accept new settings for this and other events.
IMPORTANT NOTE:
If a probe is installed in, on or near the display enclosure, due to its location, its temperature may be slightly affected by
the heat generated by the display and the electronics. Therefore, wiring a probe externally, if possible, in an area in
which the temperature is to be controlled, is preferred.
Also, if an internal probe is installed in the enclosure, then pulling the probe further out of its shield may lessen its
sensitivity to the heat generated inside the display enclosure.
If the model has two probes, to switch the thermostat control to the External probe, make sure that the function
Fn 27
is
DISABLED
.
CAUTION: Avoid exposing the temperature probes to the direct sunlight as this will dramatically affect the readings.
To PROTECT the PROGRAM AGAINST ANAUTHORIZED ACCESS :
By ENABLING the function
Fn 63
( see the FUNCTION SETUP Procedure section in the Manual ) all access to the clock
functions and to the Thermostat program via the remote control will be LOCKED-OUT. All other operation will however
remain unaffected.
In order to regain the control via the Remote Controller, disconnect the supply power for 2 seconds and then restore the
power and within 30 seconds Disable the function Fn 63.
All remote access to the clock will be unlocked.
