4.1 CIRCUIT BOARD SAT 3 - CID3 72 005
The SAT3 circuit board is used for extra functions for
which inputs and outputs are not included as standard
in the control unit of the air handling unit. All outputs
are normally open (N.O.). Maximal load: 230VAC – 4A.
The circuit board SAT3 allows for signalling of the
following by means of a potential-free contact:
•
Fan status
•
Differential pressure alarm -
•
Heating demand
•
Bypass status
Installation
SAT3 must be plugged onto the control board circuit
(see fig.1).
Attention: The SAT3 must be plugged in before
the circuit is powered. SAT must be plugged in
correctly, wrong positioning can damage both
circuits permanently.
4.2 CIRCUIT BOARD SAT BA/KW - CID3 72 004
SAT TAC5 BA/KW is a satellite circuit designed to be fitted on the main
control board. It permits control of external coils.
Installation
The SAT BA/KW must be plugged onto the control board circuit
(see Fig.2).
Attention: The SAT TAC5 BA/KW must be plugged in before
the circuit is powered. SAT must be plugged in correctly, wrong
positioning can damage both circuits permanently.
Wiring
The terminals of the SAT BA/KW are displayed in fig.3
WP WP = Cooling demand (max. 30 V-2 A)
OUT7 = 0-10 V output to control heating- or change over capacity.
OUT8 = 0-10 V output to control cooling capacity
OUT9 = PWM output to control electrical coil
T°7
= Heating coil frost protection sensor (T7)
T°8
= Cooling coil frost protection sensor (T8)
IN10
= boosted cooling OFF, (to boost external post heating coil use IN6)
IN11
= Input cooling/heating (open = heating, closed = cooling)
