•
"Minimum switch-on" - minimum time for
which the DX secondary heater is to remain
on after it has been switched on
•
"Minimum off" - minimum time for which
the DX secondary heater is to remain off
after it has been switched off
•
"Between start-ups" - the minimum time
between starts of the DX secondary heater
•
"Valve actuator" - the control voltage of the
secondary water heater valve actuator, to
which the zero
corresponds (e.g. for 2-10V controlled
actuators, set 20% so that 0% of the
controller output signal corresponds to 2V
control voltage)
•
"PID output signal" - current control of the
PID controller of the pre-heater
•
"Setpoint" - temperature setting after the
pre-heater (sensor B2/B6)
•
"Kp" - gain factor of the PID controller of the
pre-heater
•
"Ti" - pre-heater PID controller doubling
time
•
"Minimum power" - minimum controller
control from which the pre-heater is
activated
•
"Maximum power"
controller control with which the pre-heater
can operate
•
"Heater type" - type of control of the electric
preheater - the start permission for the PWM
controlled part is the signal from the
pressure switch, for
(ON/OFF) the signal from the first relay
•
"Regulated degree" - share of the power of
the PWM-controlled part in the total power
of the electric preheater
•
"Stage 1" - share of the power of the first
(ON/OFF) stage in the total power of the
electric preheater
[if any of the heater stages are not present in
the AHU, set 0% for it and distribute 100%
according to the power of the stages
present].
[for AHUs with only liquid heaters, the start
signal is available on the controller, but its
connection is not mandatory - its role is
taken over by the activation signal from the
pressure switch and thermostat].
•
"Minimum switch-on" - minimum time for
which the DX preheater is to remain on after
it has been switched on
•
"Minimum shutdown" - minimum time for
which the DX pre-heater is to remain off
after it has been switched off
•
"Between start-ups" - the minimum time
between consecutive activations of the DX
preheater
adjustment level
- the maximum
the first stage
