6. Description of Features 6.1. Basic Parameter Control The unit has a digital input for control of On/Off and three analogue inputs for control of Setpoint, Mode and Fan Speed. A change to any of these inputs will be transmitted to the air conditioner. The analogue inputs work in bands. -
Page 14: Dead Band Mode
The diagram below shows an example of the Auto/Fan function. 6.3.2. Dead Band Mode Dead Band mode is selected by setting bit switch SW2-1 to ON and activating the ‘Energy Save’ input. In this mode the unit uses high and low setpoints to control the operation of the air conditioner. The selected parameter values for Setpoint and Mode are ignored by the system. -
Page 15: Relay Outputs
6.4. Relay Outputs There are 4 relay outputs each of which has an associated LED 6.4.1. On/Off The relay and the LED both energise when the unit is ON and de-energise when it is off. The LED will flash when the unit is ON but in standby mode. -
