Boilers MAH-100, MAH-125 can be electrically connected to
indirect storage tank as follows:
• Connect DHW priority
10K
Ω
sensor NTC to terminals
3-4
on terminal block
M2
.
• Insert
10K
Ω
NTC sensor element in the sensor well of
indirect storage tank.
• Verify exchange capacity of the storage boiler coil is
appropriate for boiler power.
• Adjust DHW tempe95 °F...+140 °F (+35
°C...+60 °C) by pressing
or
on boiler Control.
IMPORTANT: set parameter P03 = 05 as described in:
"PARAMETER SETTINGS".

Note
Sensors used for this boiler are proprietary to
the manufacturer. Use of after market sensors
will diminish boiler performance.

8.9 Management of 0-10V Input
The functions with 0...10V regulator are activated by means of their parameters:
To enable 0-10V input change
P82=4
to
P82=3
,
When
P78=1
the input manages the
heating set point temperature directly.
When
P78=2
the input manages the
heating power input directly
.
Demand is activated above 3V and heating setpoint is calculated in proportion to deviation from 3 to 10 V DC, to give a
setpoint that goes from minimum to maximum.
Terminal # 9 is negative (-), terminal #10 is positive (+).
P78=1
P78 = 2
