the last settings and return to the last operating condition
prior to power off.
2. RELAYS AND RELAY CONTROL LOGIC
The “RELAY LOGIC” controls the built in relays.
A.
LO PUMP (FILTER PUMP) RELAY K-1
This relay is operated from two sources:
1. Turns on when the “HEAT” command from the
processor is present and the “JETS” command from the
processor is off.
2. Turns on from the remote time clock if the “JETS”
command is not present.
This relay will open for 30 seconds when switching from
pool to spa and from spa to pool. This is to take pressure
off pool/spa valves while they are changing. This relay
will remain closed for 2.5 minutes (fireman’s switch) after
the pump is turned off if the heater was on to allow the
heater to cool down before turning off the water flowing
through it. Any time the “JETS” command is turned on,
“LO PUMP” will turn off but will come back on when the
“JETS” command is turned off providing any of the three
conditions are met.
MASTER CONTROL UNIT FEATURES
B.
HI PUMP (JETS) RELAY K-2
“HI PUMP” relay will turn on any time it receives the “JETS”
command from the processor. When the jets off command is
received, the hi pump will turn off when these conditions are
met:
a.If still in heat mode the hi pump will go off and lo pump will turn
on.
b.If the heater was on and the heat mode is turned off at the
same time, hi pump will go off and lo pump will turn on for 2.5
minutes (fireman’s switch) and then go off unless the timer clock
is on, then it goes off for 30 seconds and back on again. Hi
pump will time out and shut down automatically in 30 seconds.
C.
AUX-1 (BLOWER) RELAY K-3
This relay can be turned on or off at any time by generating an
“AUX-1" command. Aux-1 will time out and shut down
automatically in 30 minutes.
D.
LIGHT RELAY K-6
This relay is turned on when the “LIGHT” command is present
from the processor. The light will time out and turn off
automatically in 4 hours.
E.
OZONATOR RELAY K-7
This relay is energized if hi or lo pump is on.
F.
HEATER RELAY K-12
This is the external heat command relay.
G.
AUX-2 RELAY K-4
This relay will be turned on when the “AUX-2" command is
present. Aux-2 will time out and shut down automatically in 4
hours.
H.
AUX-3 RELAY K-5
This relay will be turned on when the “AUX-3" command is
present.
I.
POOL VALVE RELAY K-9
This relay turns on when the “HEAT ENABLE” command is
present. Pool valves operate on 24 VAC so both K-11 and K-9
contacts are set up to operate from an external 24 VAC
transformer. This relay is used in pool/spa applications. The
pumps are turned off for 30 seconds while the valve is turning.
