System Set Up

2. DIP switch

Turn DIP switch 3-6 ON.

3. 2-way valve 2a (for Zone1) / 2-way valve 2b (for Zone2)

Electrically wire 2-way valve 2a and 2b to the appropriate external output terminals. (Refer to "External outputs" in 5.2)

5.4 2-zone valve ON/OFF control

5.5 Indoor unit only operation (during installation work)

1. Pipe work

1. Zone1 2-way valve 2a (local supply)
2. Zone2 2-way valve 2b (local supply)
3. Water circulation pump 2 (local supply) *1
4. By-pass valve (local supply) *2

*1 Install according to system in the field.

*2 For safety protection, it is recommended to install a by-pass valve.

Note: 1. Freeze stat function is deactivated whilst this control is ON.

Use anti-freeze solution to avoid freezing, if necessary.

2. When mixing tank and DHW tank are installed, install a

3-way valve (OUT4) in the primary water circuit.

4. Room thermostat connection

Opening /closing 2-way valve provides a simple 2-Zone control.

Flow temperature is common for Zone1 and 2.

In the case when DHW or heating operation is required prior to connection of the outdoor unit; i.e. during installation work, an electric heater in indoor unit (*1) can be used.

*1 Model with electric heater only.

1. To start operation

● Check if the indoor unit power supply is OFF, and turn DIP switch 4-4 and 4-5 ON.

● Turn ON the indoor unit power supply.

2. To end operation *2

● Turn OFF the indoor unit power supply.

● Turn DIP switch 4-4 and 4-5 OFF.

*2 When the indoor unit only operation is ended, ensure to check over the settings after outdoor unit is connected.

Note:

Prolonged running of the this operation may affect the life of the electric heater.

Heating operation mode

Zone1

Zone2

Room temp. control

(Auto adaptation) *3

● Wireless remote controller (option)

● Room temperature thermistor (option)

● Main remote controller (remote position)

● Wireless remote controller (option)

Compensation curve or flow temp. control

● Wireless remote controller (option) *4

● Room temperature thermostat (local supply)

● Wireless remote controller (option) *4

● Room temperature thermostat (local supply)

*3 Ensure to install the room thermostat for Zone1 in main room since the Room temp. control for Zone1 is prioritized.

*4 The wireless remote controller can be used as a thermostat.

Zone1

Zone2

In DHW or heating operation, the commands in the table below can be used.

IN11

IN12

Meaning

OFF (open)

Normal operation

ON (short)

OFF (open)

Switch-on recommendation*1

OFF (open)

ON (short)

Switch-off command

ON (short)

Switch-on command*2

Note:

• To activate this function, settings on the main remote controller are required.

(Main menu → Service → “Function settings” Ref. add: 0, Unit: 1)

• Heating operation mode (compensation curve or flow temp. control) requires

the optional wireless remote controller.

*1 Switch-on recommendation has following 2 modes:

Mode 7 Hot water operation

Additional boost temperature is added onto the usual DHW target temperature.

(1-Inactive (default) /2-Target temp. +3°C/3-Target temp. +5°C)

Mode 8 Heating operation

Heating ON (permitted heating with thermo ON) range is extended.

(1-Inactive (default ) /2-Thermo ON temp. +2°C/3-Thermo ON temp. +3°C)

*2 Switch-on command has following 2 modes:

Hot water operation

With electrical heater or DIP SW 1-2 ON → Target temp. : 60°C

Without electrical heater and DIP SW 1-2 OFF → Target temp. : 55°C

Heating operation

Heating is ALWAYS permitted.
