List
of
controller
inputs
and
outputs
Digital inputs:
•
R1 - the first threshold of air flow requirement, forced from an external sensor (potential-free NO contact) / supply
air filter pressure control
•
R2 - the second threshold of air flow requirement, forced from an external sensor (potential-free NO contact) /
exhaust filter pressure control
•
SAP - signal input from the FIRE control unit (potential-free NC contact)
•
ECO - signal input from the alarm control unit (potential-free NO contact)
•
TR1 - pre-heater thermostat (NC)
•
TR2 - re-heater thermostat (NC)
•
Q1D - air quality measurement (NO) (alternatively with 0-10V).
Analogue inputs:
•
Q1A - air quality measurement (0-10V signal) - the input functions interchangeably with the digital input Q1
Temperature inputs (NTC 10K sensors):
•
T1 – air intake temperature
•
T3 – air supply temperature
•
T4 – air exhaust temperature
•
T5 – exhaust vent temperature
•
T6 – GHE temperature
Digital outputs:
•
W1 - supply air fan (750W)
•
W2 - exhaust air fan (750W)
•
N1 – pre-heater (1000W)
•
N2 – re-heater (1000W)
•
GWC - ground heat exchanger actuator
•
SBP1 - heat exchanger bypass actuator, supply air duct
•
SBP2 - heat exchanger bypass actuator, exhaust air duct
•
OPERATION - potential-free contact (NO)
•
FAILURE - potential-free contact (NO)
•
RESERVE 1, 2 - potential-free contact (NO)
Analogue outputs:
•
N2 - pre-heater, three-way valve (0-10V)
•
CH - water cooler, three-way valve (0-10V)
•
SBP1 - heat exchanger bypass actuator, supply air duct (0-10V)
•
SM1 - mixing chamber actuator (0-10V)

W2 - exhaust air fan control (0-10V, PWM)
CAUTION!
The
device
does
not
provide
absolute
protection
of
the
systems
working
with
the
controller
and
the
environment
in
which
it
operates.
The
components
working
with
the
controller
should
be
connected
electrically,
in
a
manner
ensuring
safe
activation
of
protection
mechanisms,
regardless
of
the
algorithms
implemented
by
the
controller,
using,
among
other,
the
following:
•
hard-wired
control
of
the
heater
valve
actuators,
depending
on
the
activation
of
the
anti-freeze
thermostat
•
spring-return actuators for external dampers or control valves,
•
hard-wired disconnection of fans or the entire device, after receiving a signal from the SAP control unit.
•
Backup
power
supply
systems,
particularly
dedicated
to
the
device
working
with
water
heaters.
•
In
the
event
of
a
power
failure,
the
control
unit
for
the
circulating
pump
or
the
control
valve
without
a
return
spring
may
not
be
able
to
protect
the
water
heat
exchanger
from
freezing.
