Unocc HT
Return air sensor network
lost unoccupied heating
setpoint
Default:
65°F
If network communication is lost with the zone controllers, the
return air sensor will control the RTC to maintain this setpoint.
40 to 90°F (4.5°C to 32°C)
(increments: 0.5° or 5°)
Sp range
Static Pressure sensor
range
Default:
0
Static pressure transducer range. Voltage input range is 0 to 5
VDC.
0 = 0 to 1.5 in WC
1 = 0 to 2 in WC
2 = 0 to 3 in WC
3 = 0 to 4 in WC
4 = 0 to 5 in WC
Pressure
Static Pressure setpoint
Default:
0.8”WC
Bypass damper will maintain this supply static pressure set
point.
Please refer to the Viconics Zoning System Guide for
recommended settings.
0 to 2 in WC (0 Pa to 500 Pa)
(increments: 0.1” WC or 25 Pa)
SP Cntrl
Static Pressure Control
Type
Default:
BPD
Depending on the setting of this parameter, the 0-10VDC
pressure control output (labled BPD) will either have a 0VDC or
10VDC output when the fan is Off.
BPD (By-Pass Damper): 10VDC when fan is Off
FD (Variable Frequency Drive): 0VDC when fan is Off
Parameters Specific to the VZ7656H1000B Heat Pump Model
High BP
High balance point
Default value =
90 °F (
32.0 °C )
Function will only be
enabled if OS (outside air
temperature sensor) is
connected.
In
Heating or Auto mode
, it is the outside air temperature value
at which the auxiliary heat will be cut off. Above that value, only
the heat pump will be used to maintain the heating setpoint
34 to 90 °F ( 1.0 to 32.0 °C )
