For water heating coil HCW : If there are no current faults for the heating coil ("Fault on unit" shown as "No"), forced start may be activated: ● Enter an output level for HCW to start the motor valve and pump for the water heating coil Menu 8.3.3 Cooling unit 8.3.3 Cooling unit CCW Error on unit 0% No (The menu screen is different depending on which cooling unit is selected - CH, CCH, CCW, MXCU, MXHP) If there are no current faults for the cooling unit ("Fault on unit" shown as "No"), forced start may be activated: ● Set the output level for the cooling unit Menu 8.3.4 Dampers and relays 8.3.4 Dampers and relays LSF > LSA > RGS/AUX OUT > Alarm relay > VDI light > BP1 [2.00V] > Off Off Off Off Off 2.00V The following dampers may be forced open or closed via the menu: ● LSF (closing damper, outdoor air) ● LSA (closing damper, exhaust air) ● RGS/AUX OUT (flue gas damper) ● The alarm relay may be forced to trigger. ● The light in units fitted with VDI lights may be switched on and off ● BP1 (bypass damper 1) Menu 8.4 - Calibrating MPT NB: The pressure transmitters (MPT) may only be calibrated when the unit is stopped. The doors should be opened to equalise pressure with the surroundings and to ensure correct calibration. ● Select "Yes" for calibration (automatically changes to "No" again when the MPTs have been calibrated). 8.4 Calibration of MPT MPT1, P1 MPT1, P2 --- MPT2, P1 --- MPT2, P2 --- MPT3, P1 --- MPT3, P2 --- MPT4, P1 --- MPT4, P2 --- MPT5, P1 --- MPT5, P2 --- MPT6, P1 --- MPT6, P2 --- MPT7, P1 --- MPT7, P2 --- Calibrate > No Select "Yes" for calibration (automatically changes to "No" again when the MPTs have been calibrated).
