12.1 - Adjusting the
domestic hot water
temperature
The domestic hot water temperature is
adjusted by turning knob “32” shown in
figure 1. When the knob is turned, the
display, item “31” in figure 1, shows a
flashing and the temperature being
selected. The range within which the
domestic hot water can be set is 104
° F
(40 ° C) to 140 ° F (60 ° C) or from 113 ° F
(45 ° C) to 158 ° F (70 ° C) when an indirect
storage tank is used. For boiler model
45WE and 45AE, operate on knob “C” of
figure 43.
12.2 - Heating
system temperature
adjustment
The boiler provides hot water to the
heating system at the temperature set
by adjusting knob “33” as shown in figure
1 or, for boiler model 45WE and 45AE,
adjusting knob “A” of figure 43. The room
thermostat turns the boilers’ circulator
pump on in order to satisfy the heat
demand of the rooms controlled by the
thermostat. To maximize the boilers’
performance, temperature knob “33” or
item “C” in figure 43 for models 45WE
and 45AE, should be set at a value that
is just sufficient to maintain the desired
temperature of the rooms. As the weather
gets colder, progressively increase the
water temperature by adjusting knob
“33” or item “C” in figure 43 for models
45WE and 45AE. When the weather gets
milder turn the water temperature down.
This extremely simple method is suitable
for the following types of systems:
small systems with radiators where
the thermostat is installed in a room
whose temperature is characteristic
of all the other rooms;
large systems with radiators, where
each zone is controlled by its own
room thermostat. Where zone valves
are used the boiler pump is shutdown
only when all the room thermostats
are satisfied (see to an appropriate
electrical system).
large systems with low temperature
radiant panels , where each zone is
controlled by its own room thermostat.
Where zone valves are used the boiler
pump is shutdown only when all the
room thermostats are satisfied (see
to an appropriate electrical system).
CAUTION!!! If the boiler is
installed in a low temperature system
follow the settings specified in
section 5.10 or the heating system
may be damaged.
12.3 - Heating
system type
selection
The boiler is factory set for “Thermo-static
adjustment” as per section 12.2.
The heating system type can be changed
by going to the “Installers’ Menu” in
section 12.11 and changing the
parameter. One of the three following
heating modes can be selected:
-CH = 00 “Thermostatic adjustment”:
follow section 12.2;
-CH = 01 “Climatic adjustment”: follow
section 12.4 (an outdoor temperature
sensor is required);
-CH = 02 “Climatic adjustment with room
compensation”: follow section 12.4 to
12.4.6 (an outdoor temperature sensor
is required):
12.4 - Climatic
adjustment
While in the “Installers’ Menu”, set the
parameter to 01. In this mode the
heating supply water temperature,
calculated temperature in figures 40 and
41, will be adjusted automatically based
on the input from the outdoor
temperature sensor. The relationship
between the outdoors temperature and
the supply water temperature,
corresponds with the graphs shown in
figures 40 and 41. In order to change the
relationship between the supply water
temperature and the outdoors
temperature, all the parameters listed in
the sections below must be set.
12.4.1 - Climatic
adjustment:
applicable system
The “Climatic adjustment” is a sophis-
ticated way to maximize comfort and
boiler efficiency. It is suitable for the
following system types:
A - small systems, with radiators where
the thermostat is installed in a room
whose temperature is characteristic
of all the other rooms. The room
thermostat is used to make
corrections to the room temperature,
switching the boiler pump on and off.
B - Iarge systems, with radiators, where
each zone is controlled by its own
room thermostat. Where zone valves
are used the boiler pump is shutdown
only when all the room thermostats
are satisfied (see to an appropriate
electrical system).
C - small systems, with low tempera-
ture radiant panels where the
thermostat is installed in a room
whose temperature is characteristic
of all the other rooms. The room
thermostat is used to make
corrections to the room temperature,
switching the boiler pump on and off.
In this type of system it is necessary
to consider that the radiant panel
systems has an extremely high
thermal inertia. It will be necessary to
adapt the heating system and use the
“Reaction” parameter in order
to speed up any “full operations”
situation, see section 12.11.
D - Iarge systems with low temperature
radiant where each zone is controlled
by its own room thermostat. Where
zone valves are used the boiler pump
is shutdown only when all the room
thermostats are satisfied (see to an
appropriate electrical system).
CAUTION! If the boiler is
installed in a low temperature
system, follow the settings specified
in section 5.10 or the heating system
may be damaged.
12.4.2 - Climatic
adjustment
precautions
When making adjustments to change
the supply temperature, it is advisable
to first set the suggested default values
for the desired curves shown in figures
40 and 41. If these default values do
not produce a satisfactory result, then
