FOREWORD
e programmable “Immergas”“System Manager Kit”
was designed to guarantee ideal temperature conditions
at any time of day and night, for every single day of the
week, using the most economically advantageous source
of energy based on the characteristics of the installed
components and environmental conditions.
e main control possibilities are:
1. Direct system without mixed valves and without
dehumidiers with integration either through resist-
ances or boilers, and management of the solar system
with a layer.
2. System for up to 8 zones, with 3-point mixer, and
management of a high temperature zone with boiler
integration.
3. As in the aforementioned cases but with the possi-
bility of managing the solar part on two layers and a
high temperature zone.
4. As in the aforementioned cases but with the possi-
bility of managing a puer for the solar integration
of CH.
e customer can change the basic program according
to their requirements.
Programming the “System Manager Kit” is extremely
easy and a wide display screen allows you to constantly
control all set values.
