Electric Wiring; Conducting The Patching Cables - Opop ECOMAX 25kW User Manual

the connection of the flat patching cable between the input/output module and the Ecomax control panel. Connect the power
cable of the input/output module to the 230VAC distribution grid.
Physically check the running of the primary air circulation pump and the secondary heating circuit pump if present in the heating
system. Check the running of the flue gas extraction fan. Once the boiler door is opened, the fan must ramp up to 100 % of its
power. Draught must be apparent near the boiler door towards the chimney. Once the control button with the image of the fan
crossed out is pressed, the flue gas extraction fan must stop. No draught should be felt near the boiler door then.
Stack the boiler with dry wood and fire it up – see chapter 8.3 Adding firewood. Once the fire has lit up reasonably, close
the boiler door and unblock the fan function by repeatedly pressing the button showing the symbol of the crossed-out fan. The fan
will slowly start to ramp its power up, fanning up the flames in the boiler's fire chamber.
The boiler's primary heating circuit pump and the flue gas extraction motor must be electrically interconnected at the customer's
site. The interconnection may only be carried out by a person with the relevant electric engineering qualification. Space
thermostat may be individually connected to the controller, where the former must be fitted with a potential-free switching contact;
for an equithermal design an outdoor temperature sensor must be connected, to be positioned on the northern side of the building
not exposed to direct sunlight, at the height of approx. 2 m above the ground. The length of the patching cable for the outdoor
temperature sensor may be 15 m maximum, or 25 m maximum, for connection using a coaxial cable.
Equipotential bonding must be provided on all electrically conductive parts.

Electric wiring

The controller is powered by the 230V/50Hz network using a network cable with a bent plug and a CEE7/7 connector. The IEC
320 C13 network socket case accommodates a protective 2A/T tube fuse. The power part of the controller is screwed on inside
the sheet cover of the boiler, equipped with bushings and a flat patching cable for the Ecomax control panel.

Conducting the patching cables

Fix the input/output module to the boiler shell in such a way using two installation screws in such a way as to ensure the passage
holes through the sheet casing of the boiler and module are in alignment. Non-combustible silicon cables under the boiler shell
will be conducted via this opening. This concerns the main switch, the grounding wire for the equipotential bonding, boiler door
contact, emergency thermostat and the boiler output water temperature sensor.
