Power outage
ATTENTION If power is lost during a program, upon power-up the controller will be in
hold and the setpoint value will be the setpoint value prior to the beginning of the
setpoint program. The program is placed in hold at the beginning. The mode will be as
configured under “PWR UP” in the “CONTROL” group.
Digital input (remote switch) operation
Program can be placed in RUN or HOLD state through a remote dry contact connected to
optional digital input terminals, as follows:
RUN—contact closure places Program in RUN state, OR
HOLD—contact closure places Program in HOLD state
Opening the contact will cause the Controller to revert to its original state.
