Drawing 39 Connecting an external alarming device, where: 1- ecoMAX810P1-L regulator module A, 2 – external alarming device, 3 – U3 Module.
In order to provide proper operation, set appropriate value of code for signalling active alarms in the menu: Service settings>Boiler settings>Alarms Selecting a value of “127” will cause occurrence of voltage between terminals 3031 (alarm output activation) if any alarm occurs. Setting this value to “0” will prevent the boiler from activating the output in the case of alarm. It is also possible to set up the alarm output in such a way, that it was activated when one or several selected alarms occur. The value to which this parameter should be set for individual alarms is presented in the following table:
Boiler overheated
Exceeding feeder temp.
CH boiler temperature sensor damage
Feeder temperature sensor damage
Unsuccessful firing-up attempt
Fan damage
The regulator can signal alarm states by activating a peripheral device, e.g. a buzzer or a GSM device for sending an SMS - short messages. The alarm signalling device should be connected in accordance with Drawing 39, via an U3 module, to the ecoMAX810P1-L regulator, module A.
Emission sensor damage
13.13 Connecting alarm signalling
AL 1 1
AL 2 2
AL 3 4
AL 4 8
AL 5 16
AL6 32
AL7 64
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 AL1. If the output is to signal activity of several, freely selected alarm states, e.g. alarms AL2 or AL4, set this parameter as value which is the sum of the table-listed values for individual alarms (2+8=10). If any of alarms AL1, AL2, AL3 is to be signalled, set the value to “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), - connect mixer temperature sensor and mixer pump, - activate the regulator and specify appropriate valve opening time in the mixer service settings, in accordance with the servo documentation. Service settings > Mixer 1 settings > Valve opening time, - disable and enable power supply to the regulator, wait until the servo is calibrated.
