Mark Description
00 No Function -
01 3WV SWP
In case of combining Unit with swimming pool, this output is used to drive 3-way valve diverting to the
swimming
pool heat exchanger. Output ON signal when swimming pool function is operating.
02 WP3 In case of combining Unit with hydraulic separator, this output is used to drive relay of water pump 3.
03 Boiler combination In case of combining Unit with boiler, this output is used to Start/Stop it.
04 Solar out In case of combining Unit with solar panel, this output is used to drive relay of solar pump.
05 Alarm signal Output ON signal when an Alarm Code is existence.
06 SWP signal Output ON signal in case that Swimming pool function is demand ON.
07 Cooling signal Output ON signal in case that Space Cooling is Thermo-ON.
08 WP1
In case of the pipeline connected to the unit is long leading to low water ow rate, this output is used to drive
relay of a extra WP1 that can be cascaded with inside EC WP1 to o󰀨er additional hydraulic head. The extra
WP1 works equally with inside EC WP1. For Integra Unit, extra WP1 stops when 3WV DHW is ON diverting
water circulation to the sanitary tank inner coil, referring 10.1(3).
09 Heating signal Output ON signal in case that Space Heating is Thermo-ON.
10 DHW signal Output ON signal in case that DHW is demand ON or DHW Electric Heater is ON.
11 Solar overheat Output ON signal in case that solar panels overheat protection is activated.
12 Defrost Output ON signal in case that the outdoor unit is defrosting.
13
DHW re-circulation
pump
Output ON signal to drive relay of a re-circulation pump in case of re-circulation pump is available for DHW
tank.
14 Heater relay 1 Copy ON/OFF signal of Auxiliary electric heater output terminal 1.
15 Heater relay 2 Copy ON/OFF signal of Auxiliary electric heater output terminal 2.
16 c1 water ON/OFF Output ON signal in case that Water Cycle1 switch ON.
17 DHW Electric Heater Output ON signal in case the DHW Electric Heater is Enabled and meet the ON conditions.
18 3WV DHW
In case of combining Unit with DHW, this output is used to drive 3-way valve diverting to the sanitary tank
inner coil.
Output ON signal when DHW function is operating.
19 Mixing valve Close Mixing valve has 2 operation terminals of closing valve and opening valve. Optional output signal need be
congured
as function of “Mixing valve Close” and “Mixing valve Open” to drive mixing valve.
20 Mixing valve Open
21 WP2 When Water Cycle 2 is available Optional Output signal need be congured to drive relay of water pump 2.
22 3WV Cooling
In case of combining Unit with cooling fan coil, this output is used to drive 3-way valve diverting to cooling
fan coil.
Output ON signal when space cooling is operating.
23 Act1

cooling). And also meet follow condition Room actuators also Output ON:
①
Air purge
②
Anti freezing
③
Screed Drying
④
Retry operation due to anti freezing (alarm-76 , d1-31, d1-03)
⑤
Outdoor Unit defrost without Room Thermostat Thermo ON
⑥
Overrun after requiring OFF
