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
