Field Setting
(5) Thermostat Control
(5.1) X-control
When the DDC controller sends a voltage that is lower than 1,5 V, the unit stays thermostat off.
When the voltage is bigger than 1,5 V, the unit goes thermostat on.
(5.2) X-control
When the DDC controller maintains level A for more than B minutes, and the thermostat is on,
thermo off is carried out for at least C minutes. After C minutes, thermostat on-conditions are
checked.
When the DDC controller reaches level D or higher (lower for heating) and the thermostat is off
for at least C minutes (refer to thermo off conditions), thermostat on is carried out for at least E
minutes.
