On the sensor end, roll the shielding and tape so it will not contact a conductor. On the control
end, the shield should be grounded. Do not ground both ends of the shielding.
Avoid routing wiring on or near other electrical wires, conduit, motors, spark igniters or other
sources of high, intermittent voltage or current. EMI (spikes) can disrupt information flow and
retention.
Procedure for Installing Supply Sensor in Tank:
1. Install sensor into dry well utilizing thermal conductive paste.
2. Install dry well into tank stat opening.
PROVIDING 24 VAC POWER TO THE CONTROL
!!! CAUTION !!!
DO NOT connect power until
all wiring is complete
and checked.
!!! CAUTION !!!
DO NOT connect 120 VAC
to the RayTemp!!!
Resulting damage will
void your warranty.
The RayTemp requires an external power transformer connected at terminals one and two.
Complete and check all wiring before connecting this transformer. The transformer must be rated
for 24 VAC at 16 VA or higher. When 24 VAC power is applied to the control the LCD display will
be blank for a few seconds. During this time the RayTemp is configuring any modem that may be
connected. After this the opening screen appears which identifies the model number, type of con-
trol, software version, and copyright notice.
