You can replace one 4 wire sensor with two 2 wire sensors - one sensor for the differential function and one sensor for the digital display module. An additional hole will need to be drilled. The extra hole should be of the same diameter and in the same general location as the hole for the original 4 wire sensor.
Surplus item to be discontinued.
Heliotrope Pool Water Sensor with 4
conductors and Hose Clamp
This extra durable
and virtually indestructible stainless steel sensor
truly guarantees years of corrosion resistant performance. The sensor
is wired into the system and signals the controller unit with readings on the
pool water temperature.
• Maximizes pool
• Use with digital
• Used to measure
temperature of the pool's water
• Used in conjunction with the Heliotrope HelioMatic
• Control Unit - Model:
• Used as a
replacement for the Heliotrope HelioMatic Solar Pool
Control Package #1 - Model: HM-PKG
• Can be used with any Solar
Control unit that requires 10K sensors
• 2 thermistors potted in one plastic sensor well,
with each of the two wires shrink-wrapped together.
steel construction for extreme durability
• One year factory
ISD-1.0-10K should be installed in the suction line from the pool between
the pump and the filter. The dual thermistor format in the ISD-1.0-10K sensor
satisfies two functions:
1 - Water temperature for the solar
2 - Water temperature for the Display in
Two wires from one thermistor
going to the Pool Sensor position on the low voltage terminal strip and two
wires going to the Display position on the low voltage terminal strip. This can
be verified through ohm resistance.
Note: Theoretically, the 2-wire IS-1.0-10k
sensors can be used in conjunction with the display unit by incorporating two
IS-1.0-10k sensors side-by-side. The IS-1.0-10k sensor for the display can be placed anywhere in
the system (return from solar, ambient air, spa) to get a temperature reading
at the controller display module.
