Aqua-Sensor Schematic (Optional)
The Aqua-Sensor device requires a 2.5 VAC power source. This source is provided via two of the posts on the
24VAC/2.5VAC transformer (see figure 20). The two leads from the transformer are run through the same cable
grip as the 24VAC and then must be pushed into the white power connector for connection to the 2.5v power
pins on the GBE circuit board.
The wire connector from the Aqua-Sensor probe is then routed through the included cable grip and plugged into
the Aqua-Sensor terminal on the GBE circuit board. See below.
Aqua-Sensor
If you are going to install an Aqua-Sensor, you can set up the 2.5V power now.
1. Locate the power cord packed with the Aqua-Sensor. It has two spade terminals on one end of the cable
and two metal “slip in” tabs on the other.
2. Locate the cord grip.
3. The cable can be run through the cable grip and wall from either end of the cable. Make sure the end with
the metal tabs goes INSIDE the controller. The spade terminals should be coming out the top end of the
grip.
4. Locate the connector at the end of the power cord. You may have already plugged it into the board.
5. Press the two metal tabs on the end of the power cord into the open slots on the connector. They will con-
nect to the pins labeled “2.5V’ on the Base Board.The other end of the power cord with the spade terminals
should be connected to the two
2.5VAC
terminals on the transformer (see figure 20).
CAUTION - Verify wiring from terminals to circuit board are correct before applying power to
control. 24vac power must not be applied to the 2.5 vac terminals of the circuit board.
