Hydro Unit Control
3) Circulation pump control
One circulation pump (enhancing pump P2) can be connected to the unit in addition to the built-in circulation
pump P1.
You can change the settings of the built-in pump P1 and the enhancing pump P2 using DP_SW10-1, 2, and
3 in the hydro unit.
If the enhancing pump P2 is set to Non-synchronous, the pump P2 is always energized.
3-1) Controlling the built-in circulation pump P1
Pump type: DC motor, rated voltage 220-230 V, 6 speed (changed manually)
The pump operation starts under the condition below:
• When the [HOT WATER] or [ZONE1,2] button is pressed.
The pump operation stops under the condition below:
• When the [HOT WATER] or [ZONE1,2] button is pressed.
(Operation will stop fully in about 1 minute.)
The pump operation stops/restarts under the conditions shown below.
• When changing operation modes, the pump stops for 30 seconds.
3-2) Controlling the built-in pump P1 during the hot water supply operation
You can change the action of the built-in pump P1 during the hot water supply operation using DP_SW10-1.
• DP_SW10-1 OFF (Default): The pump stops as the HP for hot water supply stops.
• DP_SW10-1 ON: The pump is always energized.
3-3) Controlling the built-in pump P1 during the heating operation
You can change the action of the built-in pump P1 during the heating operation using DP_SW10-2.
• DP_SW10-2 OFF (Default): The pump is always energized.
• DP_SW10-2 ON : The pump stops when To
≥
20 °C. (Practically the HP for heating is turned off.)
3-4) Synchronized circulation pump P2
Pump type: DC motor, rated voltage 220-230 V, connectable directly up to 200W rated power output.
You can select whether the pump P2 is synchronized with the pump P1 using DP_SW10-3. The pump P2 is always
energized if the pump P2 is not synchronized.
• DP_SW10-3 OFF (Default): Non-synchronous
NOTE:
2 zone temperature control by boiler with P1 OFF is required DP_SW10-3 OFF
3-5) Controlling the enhancing pump P2
Charging the action of the enhancing pump P2 during cooling operation by setting FC64.
• FC64=“00”(Default): The pump is always energized.
• FC64=“01” : The pump is always stopped.
