Basic operation logic
There are 4 operation combination pattern for Heating & Hot water
When open signal is input, the operation status change to the next status.
For example, if current operation status is heating ON and hot water OFF, then next status to be heating OFF &
hot water OFF when pulse is input Hydro unit memorize the status of the operation pattern before changing OFF
status by close signal.
If pulse is input at operation status 2, the operation pattern in the status 3 is same pattern in the status 1.
Manually ON/OFF
If customer change operation pattern manually by remote controller, change then operation pattern will not be
same as the basic logic.
1. If customer stop operation ( Heating off and hot water off ) by the controller, then both heating& hot water
are not to be ON with close or open signal.
2. If the unit is stopped ( Heating off and hot water off ) by open signal, operation pattern will be referred to
the pattern before the unit OFF by close signal.
• When you want to turn on/off with the pulse input reflecting the operation setting on the remote control (hot water
supply, heating, or hot water supply and heating).
