supply.
EXV A position
0% = EXV closed; 100% = EXV open
In test mode this permits selection of the required position.
EXV B position
0% = EXV closed; 100% = EXV open
In test mode this permits selection of the required position.
EXV C position
0% = EXV closed; 100% = EXV open
In test mode this permits selection of the required position.
Fan speed, circuit A. Only displayed if a variable speed controller is selected in circuit A.
In test mode, this permits selection of the required speed.
Fan speed, circuit B. Only displayed if a variable speed controller is selected in circuit B.
In test mode, this permits selection of the required speed.
Fan speed, circuit C. Only displayed if a variable speed controller is selected in circuit C.
In test mode, this permits selection of the required speed.
Evaporator water pump #1 command status. Not displayed if the unit does not control a pump.
On: pump is running
Stop: pump is stopped
Forc: this item is displayed only when the unit is stopped locally (LOFF). selecting this item authorises turning on the
pump with no delay and for an unlimited length of time. The pump will remain on until any button of the user interface is
pressed: it is then immediately stopped. If the unit is in CCN control, then the pump status is displayed in turn with "Forc" if
the pump status if forced through CCN.
During the test phase, power to the pump is switched on for 10 seconds only. When the test is completed the following is
displayed:
- Fail: displayed if the test has failed because the pump was not started
- Good: displayed if the test was successful
Evaporator water pump #2 command status. Not displayed if the unit does not control a secondary pump.
On: pump is running
Stop: pump is stopped
Forc: this item is displayed only when the unit is stopped locally (LOFF). selecting this item authorises turning on the
pump with no delay and for an unlimited length of time. The pump will remain on until any button of the user interface is
pressed: it is then immediately stopped. If the unit is in CCN control, then the pump status is displayed in turn with "Forc" if
the pump status if forced through CCN.
During the test phase, ...as above
Description
When selected this item authorises return to the previous menu.
Heat reclaim condenser pump status. Only displayed when the heat reclaim option is selected.
Forc: This item is only displayed when the unit is in Local off (LOFF) mode. Selecting this item permits starting up the pump
whithout delay and for an unlimited period. The pump stays on until any button on the user interface is pressed: it is then
immediately stopped. If the unit is under CCN control, the pump status is displayed alternatively with 'Forc', if the status is
forced by CCN.
