•
"Minimum switch-on" - minimum time for
which the DX main heater is to remain
switched on after it has been switched on
•
"Minimum shutdown" - minimum time for
which the DX main heater is to remain off
after it has been switched off
•
"Between start-ups" - the minimum time
between start-ups of the DX main heater
•
"Stage 1 - Start" - minimum controller
control from which the first stage of the DX
heater starts, if it was off
•
"Stage 1 - Stop" - controller control at
which the first stage of the DX heater is
switched off, if it was switched on
•
"Stage 2 - Start" - minimum controller
control from which the second stage of the
DX heater starts, if it was switched off
•
"Stage 2 - Stop" - controller control at
which the second stage of the DX heater is
switched off, if it was switched on
•
"PID output signal" - current control of the
PID controller of the secondary heater
•
"Kp" - gain factor of the PID controller of
the secondary heater
•
"Ti" - the doubling time of the PID controller
of the secondary heater
•
"Minimum power" - minimum controller
control from which the secondary heater
starts up
•
"Maximum power" - maximum controller
control with which the secondary heater
can operate
•
"Heater type" - type of control of the
electric secondary heater - the start
permission for the PWM controlled part is
the signal from the pressure switch, for the
first stage (ON/OFF) the signal from the
first relay
•
"Minimum modulating cut-off" - the
minimum controller setting from which the
electric secondary heater is activated
•
"Regulated degree" - share of the power
of the PWM-controlled part in the total
power of the electric secondary heater
•
"Stage 1" - share of the power of the first
(ON/OFF) stage in the total power of the
electric secondary heater
[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].
