18.9 Change or add an extra sensor
Temperature sensors are real or simulated thanks to micro switches.
The affected sensors are S1-S5, Pt1 & Pt2. If a sensor is not present,
corresponding micro switch must be
ON
. If the sensor is present and
wired, put the micro switch to
OFF
position.

18.10 Remote control wiring
The AquaEfficiency can be operated by a remote controller. To enable that connect a volt free contact between
BI1 and 0V.

When the contact is open, the unit operates normally. If it is closed, primary and secondary pump are stopped
and valves get a 0% (0 volt) signal AquaEfficiency is in standby but the controller display remains activated.
18.11 Add an actuator
The 0V contact is common for both the 0-10V signal and the 24V AC actuator power supply.
