Backup Boiler Connection; Connection Of Mixers Device - ATTACK PELLET 30 AUTOMATIC PLUS Instructions For Use Manual

CONNECTION OF MIXERS DEVICE

During installation work on the mixer, make sure that the boiler does not
overheat. This can happen due to insufficient heating water flow.
We recommend setting the position of the valve to full opening before
starting work. This ensures maximum heating water flow.
The controller only works with mixing drives that are equipped with end limit switches.
The use of other drives is prohibited. Drives with a full time range of 30 to 255 s can be
used. Description of mixer's connection:
• Connect the temperature sensor of the mixer,
• connect the electric pump of the mixer,,
• activate the controller and select the appropriate service in the service menu:
Service settings→Setting of mixer 1
• Set the valve opening time in the mixer settings (this should be written on the
nameplate of the servomotor, i.e. 120 s)
• connect the mixer to the el. controller network and activate the circulation pump,
• choose the direction in which the servomotor closes and opens. To do this, switch the
button on the manual control and find a position in which the temperature of the
mixing circuit is maximum (controller in the 100% open position). Now find a position
in which the temperature of the mixing circuit is minimal (controller in position 0%
open). Remember this configuration to verify that the connections are correct later.
• disconnect the controller from the el. network
• connect the el. power supply of the mixer and servomotor with switch and enter the
value of the servomotor specified by the manufacturer. Do not swop the opening
direction of the mixing valve with the closing direction,
• connect the controller to the el. network and switch it to "STAND-BY" mode,
• check that the wires for opening and closing the mixing valve have not been
interchanged. Enter the Manual control menu and open the mixer by selecting MIX 1 -
Open = ON. After opening, the circuit temperature should increase. If not, unplug the
power cord. energy and wires (Caution: another cause may be incorrectly connected
mixing valve, check the correct connection with the manufacturer's documentation).
Circulation pump connection
The DHW circulation pump should be connected via a relay to terminals 46-47 of the
power module.
To switch on the circulation pump control, set the H outputs for pump control in the
menu: Service settings
Remote control connection
It is possible to equip the controller with an ecoSTER TOUCH room panel, which has the
