Loading...Why can't I access the McQuay Controller CSM user interface?
If you cannot access the McQuay Controller CSM user interface despite having correct settings in your browser, it might be because the IP address of your computer is not set to be one number away from the IP address of the CSM. To resolve this, set the IP address of your computer to be one number away from the IP address of the CSM.
What to do if the McQuay MicroTech II CSM user interface does not appear?

How to connect my computer to McQuay MicroTech II CSM over Ethernet?
If you're having difficulty connecting your computer to the McQuay Controller CSM over an Ethernet connection, it could be because the computer’s IP address and subnet mask are not compatible with the CSM’s IP address and subnet mask. Make sure that the subnet masks are exactly the same on both devices and that the IP addresses are close enough to be on the same subnet.
What to do if McQuay Controller unit does not leave Fan Only and enter Heating operating state?
If your McQuay Controller unit remains in Fan Only mode and doesn't switch to Heating, check the Htg Status= parameter in the System menu to ensure it indicates “Htg Ena.” Also, the current value of the Ctrl Temp= parameter must be below the Eff Htg Spt= by more than half the Htg Deadband= parameter in the Zone Heating menu. If the Ctrl Temp= is not below the Eff Htg Spt= by more than half the Htg Deadband= parameter in the Zone Heating menu, the Eff Htg Spt= parameter must be adjusted accordingly to enable heating operation. If the unit still does not enter the Heating operating state, the MCB is likely defective.
What to do if McQuay MicroTech II Controller unit does not leave the Off Alm operating state?
If your McQuay Controller unit remains in the Off Alm operating state, first check the Active Alarm 1 menu for any active “faults.” The alarm condition must be corrected and the “fault” cleared before the unit can be started. If the Active Alarm 1 menu indicates “None” or an alarm type other than a “fault” and the UnitStatus= parameter in the System menu continues to indicate “Off Alm”, the MCB is likely defective.
What to do if McQuay Controller unit does not leave the Off Man operating state?
If your McQuay Controller unit remains in the Off Man operating state, check the Ctrl Mode= parameter in the System menu. If it is set to “Off”, the UnitStatus= parameter indicates “Off Man.” If the Ctrl Mode= parameter in System menu is set to anything other than “Off” and the UnitStatus= parameter in the System menu still indicates “Off Man.”, the MCB is likely defective.
What to do if McQuay MicroTech II Controller unit does not leave the Off Sw operating state?
If your McQuay Controller unit remains in the Off Sw operating state, and terminal 101 is not made to 104 on TB2 (binary input MCB-BI2 is off) and the UnitStatus= parameter continues to indicated “Off Sw”, the MCB is likely defective.
What to do if the McQuay MicroTech II Controller MCB is suspected to be defective?
If you suspect the McQuay Controller MCB is defective, perform a 'cold' reboot by removing the MCB battery and cycling power to the controller.
What to do if I get a battery warning on my McQuay MicroTech II?
If you receive a battery warning on your McQuay Controller, it means the battery is reaching the end of its useful life and should be replaced within 14 days.
What to do if Error LED remains on after battery replacement in McQuay MicroTech II Controller?
To address this issue, cycle power to the MCB. Also, note that the battery is tested at two minutes after midnight each day. Alternatively, issue a battery test command with a PC using the MicroTech II Service Tool.
