DF18060701
This option allows Hydro Unit to be controlled either Setting temperatures or Capacity.
Control of Setting temperature
• DN 680 is set to “1”.
• Set the input method for each setting temperature.
• Allocate the temperature of 0 to 10 V, and also set its resolution.
( )*1: AIO-Type ( )*2: HWT-110
*3: In actual operation, it would be restricted by DN setting which related to water / room temperature control.
Capacity direct control
• DN 680 is set to “2, 3 or 4”.
