Step Display
Description
Values
17
Maximum voltage of the heating output:
Display shows
“max vdc analog output heating”
and the value of the
minimum voltage of the heating ramp.
Please select the desired value of the maximum voltage of the heating
ramp. (This is the “span” value)
The maximum value is restricted by the minimum value. (step #16)
Range: 0.0 to 10.0 Volt
Increment: 0.1 Volt
Default value: 10.0 Volt
18
Set signal for 4 pipe cooling system:
(If ‘’
4P
’’ has been selected at step #8)
Display shows
“select 4 pipe cooling signal”
.
Cooling symbols is also
displayed.
Select which cooling signal output you want for your 4 pipe system.
You can choose analog or on/off output.
If you select analog,
AO1
will be set in cooling.
If you select on/off,
TO1
will be set in cooling.
If you have selected on/off signal, go directly to step #21.
Default value: Analog
19
Minimum voltage of the cooling output:
Display shows
“min vdc analog output cooling”
and the value of the
minimum voltage of the cooling ramp.
Please select the desired value of the minimum voltage of the cooling
ramp. (This is the “zero” value)
The minimum value is restricted by the maximum value. (step #20)
Range: 0.0 to 10.0 Volt
Increment: 0.1 Volt
Default value: 0.0 Volt
20

Default value: 10.0 Volt
21
Set local reheat signal
Display shows
“set local reheat signal”
.
Heating symbols is also
displayed.
Select which signal output you want for reheat.
You can choose OFF (no signal selected), ANALOG heating only,
ANALOG heating & fan, ON/OFF heating only, ON/OFF heating & fan,
PULSE heating only, PULSE heating & fan output.
If you select analog (& fan),
AO3
will be set in reheat.
If you select on/off (& fan) or pulse (& fan),
TO3
will be set in reheat.
If you have selected analog (& fan) signal, go directly to step #22.
If you have selected on/off (& fan) or pulse (& fan) signal, go directly
to step #24.
If you have selected OFF, go directly to step #26.
Default value: Off
