Table 18: MS8350 Conguration 5 / 9 Parameter Details.
Conguration Parameters Default Value Signicance and Adjustments
Cooling CPH (Cooling Output Cycles Per
Hour)
Default Value: 4 CPH
CPH is used to “modulate” On/Off outputs controlling equipment such as compressors.
When the Room Temperature is within the Proportional Band, the output performs 3 or
4 CPH. A higher CPH represents a higher accuracy of control at the expense of wearing
mechanical components faster.
The CPH does not limit the number of Cycles Per Hour. It is limited by the “Anti short cycle”
parameter. 4 CPH is typical for Rooftop applications.
Range: 3 to 4 CPH
Control Type (Control Output for FCU
Valves)
Default Value: On/Off
Defines type of control output for type of valves installed for the FCU application
On / Off: normally opened or normally closed 24 Vac 2 position valves
Floating: modulating 3 wires control of 24 Vac floating valves
Analog: analog modulating control of 2-10 Vdc valves
Choices: On/Off, Floating and Analog
BO8 Out Time (BO8 Aux Output Time Base)
Default Value: 15 minutes
Sets reheat output time base. Valid only if reheat sequences are enabled.
Choices: 10 sec or 15 min
