Programming override
There are three ways to override the existing program:
1. "HOLD" function:
• Press the "HOLD" button.
The programming (
ON, OFF, SETBACK) is eliminated.
The Setpoint remains at the set temperature.
No change can be made to the programming on the display
except adjustment to the temperature Setpoint as long as the
"
HOLD" function is active.
Pressing "
HOLD" will not alter your program setting.
• Press the "up" or "down" buttons to change the temperature.
To return to normal operation press "
HOLD" again.
The display returns to the programmed setpoint and the "
HOLD"
logo disappear.
HOLD FUNCTION EXAMPLE 1:
If a Zone Manager is in an OFF period.
Schedule:
8:00 AM ON Period Setpoint = 23
° C
10:00 AM OFF Period
3:00 PM ON Period Setpoint = 26
° C
5:00 PM OFF Period
The system is in "
OFF" mode and it is 11:00 AM.
User depresses the "
HOLD" button.
The OFF period is exited and the control resumes in "
COOL"
mode with a setpoint of 23
° C.
Any change the user makes will remain in effect until the "
HOLD"
button is pressed again to cancel the "
HOLD" function.
So if the user presses the setpoint "up" button and changes the
setpoint to 24
° C, the system will remain at 24 ° C until the "HOLD"
button is pressed.
The "
HOLD" function is not active and the time is 3:30 PM and
the system is operating in "
COOL" mode at a setpoint of 26 ° C.
If the user presses the "
HOLD" button, the "ON" period is canceled
and the unit contiunues to operate at 26
° C in "COOL" mode until
the "
HOLD" button is pressed to cancel the "HOLD" function.
