19. CONNECTING AN EXTERNAL STORAGE BOILER
(for models HT 1.120 - HT 1.240 - HT 1.280)
The mono-thermal boilers 1.120 – 1.240 – 1.280 can be connected to an external storage boiler as they are factory-fitted
with a powered three-way valve.
Hydraulically connect the storage boiler as shown in figure 13.
Connect the DHW priority NTC sensor, supplied as an accessory, to terminals 5-6 of terminal block M2, after removing
the heating element (figure 13).
Insert the sensitive element of the NTC probe into the relative trap in the storage boiler.
DHW temperature can be adjusted directly on the control panel of the boiler by pressing buttons
+/-
in figure 1.
