M
odularity is perfect when an extension of capacity becomes required as the building cooling/heang demand evolves. 6
units can be controlled in group. The group con
trol system can control and view the operaon of the enre system only by
connecng the master to the wire controller. If the DHW funcon is required, the water tank can only be connected to the
master unit water circuit through a three-way valve, and controlled by the master unit. If AHS is needed, it can only be
connected to the master waterway and controlled by the master unit. The Tbt1 temperature sensor must be installed in
the parallel syste
m (otherwise unit cannot be started). If the balance tank is too large, Tbt2 needs to be added in order to
improve the control accuracy. Tbt2 is set in the lower part of the balance tank. The water inlet and outlet pipe joints of
each unit of the parallel system should be connected with so c
onnecons and one-way valves must be installed at the
water outlet pipe.

Part 1 - General Informaon
Space heang
All salve units can operate in space heang mode. The operaon mode and seng temperature are set on the user
interface(2). Due to changes of the outdoor temperature and the required load indoors, mulple outdoor units may
operate at different mes.
In cooling mode, SV3(23.1) and P_C(23.2) keep OFF, P_O(5) keeps ON;
In heang mode, when both ZONE 1 and ZONE 2 work, P_C(23.2) and P_O(5) keeps ON, SV3(23.1)
swi
tches between ON
and OFF according to the set Tw2.
In heang mode, when only ZONE 1 works, P_O(5) keep ON, SV3(23.1) and P_C(23.2) keep OFF.
In heang mode, when only ZONE 2 works, P_O(5) keep OFF, P_C(23.2) keep ON, SV3(23.1) switches between ON and OFF
according to the set Tw2.
Domesc water heang
Only master unit(1.1) can operate in DHW mode. T5S is set on the user interface(2). In DHW mode, SV1(3) keeps ON.
When master unit operated in DHW mode, slave units
can operate in space cooling/heang mode.
AHS control
AHS should be set via the dip switches on main board; AHS is only controlled by master unit. When master unit operates in
DHW mode, AHS can only be used for producing domesc hot water; when master unit operates in heang mode, AHS can
only be used for heang mode.
1) When AHS is set valid only for heang mode, it will be turned on in following condions:
a. Turn on BACKUPHEATER funcon on user interface;
b. Master unit operates in hea
ng mode
. When inlet water temperature is too low or ambient temperature is too low, the
target leaving water temperature is too high, AHS will be turned on automacally.
2) When the AHS is set valid for heang mode and DHW mode. It will be turned on in following condions:
When master unit operates in heang mode, condions of turning on AHS is same as 1);
When master unit operates in heang mode, if T5 or ambient temperature is too low, target T5 temperature is too high,
AHS will be turned on au
toma
cally.
3)When AHS is valid, and the operaon of AHS is controlled by M1M2.
When M1M2 closes, AHS is turned on. When master unit operates in DHW mode, AHS can not be turned on by closing
M1M2.
TBH control
TBH should be set via the dip switches on main board. TBH is only controlled by master unit.
1) When the TBH is set to be valid, TBH can be turned on via TANKHEATER funcon on the user interface; In DHW mode,
TBH will be turned on automacally when the inial domesc wat
er tem
perature T5 is too low or the target domesc
water temperature is too high at low ambient temperature.
2) When the TBH is set to be valid, M1M2 can be set to be valid on the user interface. TBH will be turned on if MIM2 dry
contact closes.
Solar energy control
Solar energy is only controlled by master.
Hydraulic module recognizes solar energy signal by judging Tsolar or receiving SL1SL2 signal from user interface. The
recognion method ca
n
be set via SOLAR INPUT on the user interface.
1)When Tsolar is set to be valid, Solar energy turns ON when Tsolar is high enough, P_s starts running; Solar energy turns
OFF when Tsolar is low, P_s stops running.
2)When SL1SL2 control is set to be valid, Solar energy turns ON aer receiving Solar kit signal from user interface, P_s
starts running; Without solar kit signal. Solar energy turns OFF, P_s stops running.
