Drawing 40 Connecting an external alarming device,
where: 1
– ecoMAX800 regulator, 2 – external alarming
device, 3 – U3 Module, consisting of relay RM 84-2012-
35-1006 RELPOL and base GZT80 RELPOL.
If the regulator is to control an
external alarming device, you must
set the parameter
auxiliary boiler off
temperature to “0”
MENU -> SERVICE SETTINGS ->
BOILER SETTINGS -> AUXILIARY
BOILER ->

To guarantee proper operation, set an
appropriate value of the parameter

signal code
Choosing a value of 31 causes voltage to be
fed to contact 30-31 if any alarm occurs.
After setting this parameter to „0”, the
regulator will not supply voltage in the case
of any alarm.
The 30-31 contact can be configured so that
voltage was supplied there only if one or
more alarms occur. The value to which this
parameter should be set for individual alarms
is presented in the following table:

Example: if you set the value of the
parameter to „8”, the voltage will be supplied
to the contact only if alarm AL4 occurs.
Setting “1” will cause the contact to signalize
only alarm “1”. Should the contact signalize
several alarms, e.g. AL2 and AL4, sum up
the values corresponding to individual
alarms, i.e. you should set 2 + 8 = 10. If
alarms AL1, AL2 and AL3 are to be signalled,
set the parameter to “7”, as 1 + 2 + 4 = 7.
13.14 Connecting mixer
The regulator cooperates only with servos of
mixing valves equipped with limit switches. It
is prohibited to use different servos.
Permitted servos are those which make a full
revolution in 30 - 255 s.
Description of connecting a mixer:
- disable power supply to the regulator,
- determine the direction in which the servo
opens/closes
and make an electric
connection between the mixer and the
regulator, in accordance with Drawing 31,
and with the documentation provided by the
valve servo manufacturer (do not confuse
the valve direction of opening with the
direction of closing). 0
- connect mixer temperature sensor and
mixer pump.
- turn the regulator on and set an
appropriate
valve full opening time in the
mixer service settings, in accordance with
the servo manual.
- disable and enable power supply to the
regulator, wait until the servo is calibrated.
During the calibration, the servo is closed by
the
valve full opening time. Calibration is
signalled in the MENU Information – mixer
info by sign “CAL”.
- make sure that the servo opens in the
correct direction. To do so, open MENU
Information and go to tab info-mixer, or
enter the regulator manual control. If the
mixer does not open in the correct direction,
change the electric connection.
- disable and enable power supply to the
regulator, wait until the servo is calibrated.
- set the mixer parameters in accordance
with point 16.
