DESCRIPTION
212
INTAC Address RANGE: 1 to 247 1 Modbus Address for external RS-485 network
213
INTAC Baud Rate 9600
19200
38400 x
301
Room Prop Band* RANGE: 0% to 100% RH 25% Space or return air proportional band
302
Room Hysteresis* RANGE: 1 to 50 3 When menu 301=0 this sets the dead band for on/off control
303
Room Integral* RANGE: 0.00 to 60.00 5.00 Space or return air integral term in units of minutes/repeat:
Increasing reduces ramp rate.
304
Room Derivative* RANGE: 0.00 TO 9.99 0.00 Space or return air derivative term in units of minutes: 0 is the
recommended value
305
Cycle Time* RANGE: 1 to 240 Seconds 1 or 60 Default is set at 1 second for SCR control
306
Duct Prop Band* RANGE: 0% to 100% RH 25% Supply air Hi-Limit proportional band
308
Duct Integral* RANGE:0.00 to 9.99 0.00 Supply air Hi-Limit integral term in units of minutes/repeat:
Increasing reduces ramp rate
309
Duct Derivative* RANGE: 0.00 to 9.99 0.00 Supply air Hi-Limit derivative term in units of minutes:
0 is the recommended value
310
RH Input Filter* RANGE: 0 to 60 seconds 1 For attenuating a noisy humidity signal this averages the humidity
inputs over a set time period to increase the stability of the output
502
Control Source Transmitter Varies Controller receives analog relative humidity signal from a wall or
duct type humidity sensor
Process Signal Varies Controller receives an analog % demand/power level signal from
building management system or a separate humidity controller.
The INTAC
®
will only use the main analog input on plug J2.
503
Water Sensor K Type Option Standard type K thermocouple used in all applications
J Type Type J thermocouple
T Type Type T thermocouple
None No water sensor input available
504
RH Sensor Current Varies Used when an external demand signal or a humidity sensor is a
mA current type of signal on plug J2 terminal 2 and 3
Voltage Varies Used when an external demand signal or a humidity sensor is a
VDC type of signal on plug J2 terminal 1 and 3
