Installation instructions
INSTALLATION / SUPPLY OF PANEL BOARD
(code 44913)
GENERAL FEATURES AND STANDARD SUPPLY:
- Microprocessor circuit board with alphanumerical four line LCD display, keyboard and 6 indicator lights indicating
activation of servomechanisms.
- EPROM non-volatile memory (in case of a power outage, all settings remain valid). Memorised data remains in the
memory for about 10 years without power.
- Wiring board for electrical connections.
- Basic probe supplied:
- 4 PTC probes with insulation (three x 3 m long, code 95900528; one x 5 m long, code 95001511)
- 1 PT1000 probe for measuring flue gas temperature 4 m long, code 95001503
- Self-diagnosis program for incorrect installation or fault for PTC temperature probes.
- 1 mechanical safety thermostat with manual reset.
- Limit switch to join to door opening mechanism (TKS).
OPERATING MODES:
The circuit board
makes it possible to manage three different operating modes:
1 HEATING ONLY.
2 H PRODUCTION OF DOMESTIC HOT WATER with single coil storage tank or H PRODUCTION
OF DOMESTIC HOT WATER with double coil storage tank with management of support SOLAR PANEL SYSTEM.
3 H PRODUCTION OF DOMESTIC HOT WATER
with combined tank
(TANK in TANK) or H
STORAGE TANK (PUFFER), both with the possibility of having a coil and its control of SOLAR PANEL SYSTEM
as support.
Before commissioning the boiler, you must choose the operating mode and follow the instructions for configuration of
the board according to the type of system to be managed.
See diagrams on page 23.
BOARD SUPPLY:
The circuit board has the following inputs:
1 general 230 Vac power supply input
2 probe S1 input for solar panel temperature measurement
3 probe S2 input for buffer or storage tank low point temperature measurement (solar heat exchanger)
4 probe S3 input for buffer or storage tank high point temperature measurement (DHW production)
5 probe S4 input for BOILER FLOW temperature measurement
6 probe S5 input for BOILER RETURN temperature measurement
7 wood loading door microswitch contact input (TKS)
8 room thermostat or chronothermostat input for winter heating system management
9 FLUE GAS TEMPERATURE probe input.
The board has the following outputs to control the servomechanisms:
1 solar panel pump output (Ps) - J1
2 buffer or storage tank pump output (Pb) - J2
3 heating system pump output (Pi) - J3
5 recirculation pump output (Pr) - J4
5 free output - J5
6 fan output - J 6
7 auxiliary boiler output (gas/oil fired) - J7
