1. Meter reading:
Press and hold the button – the display panel will show letter E followed by 4 digits
separated by a hyphen (actual operating time of the device), ie. E..0..2..-..1..5 means
that the device was actually working for 2 hours and 15 minutes from the last time
the meter was zeroed.
2. Meter resetting:
Press and hold the button until E 00-00 comes up.
Setting permanent local mode
The device has been designed to work in a set, therefore, it will start searching for an IR
transmitter signal immediately after being turned on ( icon will start flashing). If the
device does not find an active IR transmitter, the diode will keep flashing.
In order to turn it off, press and hold the button until the diode stops flashing which
will mean that the controller is no longer searching for the IR transmitter and will keep
working in the local mode only.
In order to go back to work with IR transmitter, press and hold the button.
REMOTE MODE OPERATION (WITH IR TRANSMITTER)
Controller should start searching for an IR transmitter signal immediately after it has
been turned on – this is indicated by icon flashing on the display panel. Should this not
happen, press and hold the button until the icon starts flashing.
After being connected, the zicon will stay on and a dash will appear.
When working in the remote mode, buttons and are not active (except when using
the
Timer Function
).
Button :
– press it short to turn the device off
– press and hold to switch to the
Local Mode
.
Timer Function.
Timer in the
Remote Mode
is operated in exactly the same way as in the
Local Mode
,
meaning that it is operated via the ZX4 controller:
– press button to activate the
Timer
– press button a few times to modify
Timer
operating time
– press buttons to set the required temperature level during Timer operation (see:
Local Mode
operation –
Timer Function
).
The controller will automatically switch to the
Remote Mode
on expiry of the set time.
Use of the remote transmitter
Detailed description of the basic and advanced features of the IR transmitter depends on
a given type (please see user manual attached to your IR transmitter).
Examples of features of an IR transmitter – type DT-IR1
– control of temperature inside the room (in
Local Mode
the device controls the
temperature of the radiator)
– possibility to program two temperature settings:
Comfort
and
Economical
and easy
switch from one to the other
– automatic temperature adjustment program for
Comfort
and
Economical
setting
during a 24hour period (24-hour timer)
– automatic timer program
– automatic
Anti-freeze
program with possibility to adjust the operation threshold
– possibility to adjust the temperature sensor according to the specific conditions of
a given interior (calibration feature).
No signal detection (automatic feature):
The transmitter sends a controlling signal every 10 minutes in order to check the quality
of communication between the two devices. Interruption or lack of 3 subsequent signals
(30 minutes) will result in automatic changeover of the ZX4 controller
to the
Local Mode
with the “0” setting. The controller will wait for com-
munication to resume (display panel will show “0” and icon will start
flashing). Having received the controlling signal, the device will automati-
cally return to remote operation.
Adjustment of ZX4 controller address (communication channel no)
In order for both IR transmitter and ZX4 controller to co-operate successfully, both
devices must have identical addresses. In order to change the address, please follow
these steps:
1. Turn the device on and disconnect it from electricity (unplug it)
2. Press and hold buttons and , plug in the device and wait 5 seconds
3. The LED display will show the the current address i.e. A0. Set the selected address
number with the or buttons (the same address should be set in the controller).
– Numbers 0 to 3 are addresses dedicated to DT-IR1 transmitters
– Address A4 is dedicated to other IR transmitters available on the market
– Address A5 works in such a way that controller ZX4 will not verify the device
address and it will execute all successfully received commands regardless of the
transmitter address.
