5.4 Control Connections
Each controller can operate either as a stand alone unit or as part of a BMS managed control system. To allow
for this level of control complexity, 7+1 control inputs are provided in the basic controller.
The following list identifies the 7 controls in their priority order;
Caretaker Demand
Slave Demand & Follower Demand
Rain Sensor Demand
Day to Day & Thermostat & 0-10V analogue
In addition to this further manipulation of the inputs is provided by the Auto/Manual selection input.
All control connection devices must be volt-free and capable of switching 24v DC at a nominal current of 10mA.
Cable distance is not of any real concern. However, it is recommended that the maximum control cable distance
be limited to around 500M.

Caretaker Demand
Connecting CD to 0V will cause the controller to close all attached actuators. The controller will not
respond to any other inputs until CD is disconnected.
The actuator power is automatically timed off after a period of 180 seconds (factory adjustable). This is
a sufficient length of time to ensure most actuators achieve their fully closed position.
