3.17 - OPTIONAL MASTER PANEL BOARD
14 Main switch with indicator light
16 General fuse
18 Burner switch
19 P1 C.H. pump switch (cascade)
The main switch 14 powers the board and the equipment con-
nected to it.
The switches 18 and 19 control the burner and P1 pump if the
boiler operates in cascade.
The switches 20 and 21 control the Z1 pump (direct) and Z2
pump (mixed).
The thermostat adjusts the working temperature of the boiler:
to achieve this, the thermostat must be placed at maximum
full-scale pos. 33 .
20 Pz1 direct zone C.H. pump switch
21 Pz2 mixed zone C.H. pump switch
33 Working thermostat
35 Safety thermostat
Modulation of the burner will be managed by heat control.
The electric power line of the boiler's control board must have a
switch with protective fuses.
For use of the panel board, see the system manager instruction manual
The heating controller probes (boiler, storage tank, external,
flow) are included in the supply; the ambient probes 1 and 2
are optional; the mixing valve and relative control motor are not
included in the supply. Should ambient probes be mounted (optional), the room tem-
perature will only be determined with the boiler curve set by
the program.
The optional panel board of the TERNOX 2S boiler automati-
cally switches the burner off when the temperature in the boiler
reaches the value set on the heating controller.
It also manages the pump to fill a storage tank for DHW pro-
duction.
The heating systems are managed automatically based on the
data detected by the boiler, external, ambient and flow probes.
The high temperature zone C.H. pump is made ready for oper-
ation by the control switch pos. 20, and will only switch off when
the temperature set on the heating controller has been reached.
The low temperature zone C.H. pump is made ready for operation
by the control switch pos. 21, and will only switch off when the
temperature set on the heating controller has been reached.
The storage tank charge pump for DHW production switches on
automatically and will only switch off when the temperature set
on the heating controller has been reached. The panel is set up to manage the modulating burners.
With this system configuration, the heating controller is capable
of checking:
- direct zone system; the control unit commands the C.H. pump.
The room temperature is controlled by the programming
curves set in the heating controller;
- one zone system with motorised mixing valve: the flow probe
(downstream the mixing valve) must be fitted; the control unit
commands the C.H. pump and the mixing valve. The room
temperature is controlled by the programming curves set in
the heating controller;
- DHW production through storage tank;
- anti-legionella function with increase of water temperature
in storage tank (function not enabled in factory, but can be
enabled by customer).
