Connecting the Heater Switch to Control Temperatures
Overview
The primary means of controlling the heater is using the Hand-Held Controller. If there is no
Hand-Held Controller in the system, the heater switch provides an alternate method.
This Switch can be also used in conjunction with the Hand-Held Controller to provide maximum
temperature limits for the pool and spa. Control by this Switch is primary over the Hand-Held.
Procedure
Wire the heater thermostats to the blue connectors visible
on the front of the Valve/Pump Switch, as shown.
Set limits on the heaters themselves, so that when
the Switch powers the heaters, they will reach the
temperatures you have set.
Make temperature adjustments at the heaters themselves.
If Connecting an External Timer:
Overview
You can add an external timer to a circuit, converting it from
“on-demand” control to timer control. External timers are
available from Intermatic but are not included with the I-
Wave system. When connected to the system, the external
timer powers Relay 1 on and off according to its time
settings.
Procedure
Connect your timer to Relay 1 on the back of the Valve/
Pump Switch Mechanism, as shown in the circled area of
the illustration at the right.
