What to do if my Multistack MS085XC has high discharge pressure (HP)?
If your Multistack chiller is showing high discharge pressure, you should check the strainers in the condenser headers and verify the condenser water flow.
What to do if the Multistack Chiller is 'Waiting For Chilled Water Flow'?
If your Multistack chiller displays a 'Waiting For Chilled Water Flow' message, you should: * Check the chilled water pump. * Check the flow switch operation. * Inspect the filter strainers. * Check TB11 inputs #3 - #7.
What to do if my Multistack MS085XC has low suction pressure (LP)?
If your Multistack chiller indicates a low suction pressure, examine the refrigerant charge for leaks and inspect the expansion valve.
What to do if my Multistack Chiller displays 'Waiting For Condenser Water Flow'?
If your Multistack chiller is displaying 'Waiting For Condenser Water Flow', verify the condenser water pump, check the flow switch operation, inspect the filter strainers, and check TB11 inputs #3 - #8.
Why is my Multistack MS085XC Chiller at 100% demand all the time?
If your Multistack chiller is constantly at 100% demand, check the entering chilled water sensor and verify the set-points in the system variables.
Why is my Multistack MS085XC experiencing excessive cycling?
If your Multistack chiller is cycling excessively, check the VSP setting in the system variables, verify the entering CHW sensor location, and look for system problems such as low water volume or low load.
How to troubleshoot a 'Circuit Fault' on a Multistack Chiller?
To troubleshoot a circuit fault on your Multistack chiller, check the components in the control circuit, inspect the wire crimps in the control circuit, and verify the ratio of HP to LP.
What to do if my Multistack Chiller has low chilled water temperature?
If your Multistack chiller has a low chilled water temperature, check the LCHW sensor, verify the set-points in the system variables, and check for any flow restrictions.
What to do if my Multistack MS085XC Chiller shows 'No Demand'?
If your Multistack chiller indicates 'No Demand', check the entering CHW sensor, verify the set-points in the system variables, and check the sensor location.
What to do if my Multistack Chiller has low suction temperature?
If your Multistack chiller reports a low suction temperature, check the suction sensor, verify the set-points in system variables, and check for flow restrictions.
