The PM7600B Program Module allows the
W7600 System to control discharge air tempera-
ture and static pressure in variable air volume air
handling applications by modulating, energizing
and de-energizing fan, heating and cooling stages.
■
For use with Network Compatible W7600A-F 2XXX
Control Modules only.
■
Provides programming of control parameters and
alarm annunciation through the S7600 Keyboard
Display Module.
■
Demand limit control function via setpoint bump.
■
Provides P+I+D control of discharge air temperature
and duct static pressure.
■
Controls up to twelve stages of cooling and six stages
of heating.
■
Controls up to four compressors.
■
Provides modulating control of heating, cooling, fan
and economizer.
■
Provides reset based on space, outdoor or return air
temperature.
■
Controls liquid line solenoid valves and compressor
unloaders.
■
Inputs and outputs are user selectable for customiz-
ing the W7600.
■
Automated remote reporting by using a personal
computer and ZM7603 Remote Monitoring Software.
■
Communicates on Honeywell 2-Wire CNAP
Network.
■
Digital outputs can be network controlled for light-
ing or start/stop control.
■
Uses economizer for free cooling.
■
Controls chilled water and/or condenser water pump.
■
Monitors compressor, heat, water flow, proof of
airflow and dirty filter safety switches.
■
Monitors discharge air, space air, outside air, and
condenser inlet water temperatures.
■
Return air fan control, modulating or floating, from
velocity or velocity pressure.
■
Innovative velocity pressure control algorithm for
optimum return air flow tracking control.
■
Indoor Air Quality (IAQ) input signal allows out-
door air damper minimum position to be reset.
■
Staged, floating or modulating control of preheat
coil provided in outside air duct.
