prOductiOn
The DIEMATIC EVOLUTION control panel includes the “priority
DHW” function, and can therefore be completed with 1 or
2 DHW sensors - package AD212 for the control of one or
2 independent tanks.
To connect more than 3 heating circuits to a cascade installation,
one of the MCA 160 IniControl 2 boilers in the cascade must
be replaced with one (or several, depending on the number
of additional circuits to be managed) MCA 160 DIEMATIC
EVOLUTION boiler(s) (see example in the hydraulic diagram on
page 36).
