5.1.1 Space heang
The ON/OFF signal and operaon mode and temperature seng are set on the user interface. P_o (6) keeps running as
long as the unit is ON for space heang, SV1(4) keeps OFF.
5.1.2 Domesc water heang
The ON/OFF signal and target tank water temperature (T5S) are set on the user interface. P_o (6) stops running as long as
the unit is ON for domesc water heang, SV1(4) keeps ON.
5.1.3 AHS (auxiliary heat source) control
The AHS funcon is set on the indoor unit
1) When the AHS is set to be valid only for heang mode, AHS can be turned on in the following ways:
a. Turn on the AHS via BACKHEATER funcon on the user interface;
b. AHS will be turned on automacally if inial water temperature is too low or target water temperature is too high at low
ambient temperature.
P_o (6) keeps running as long as the AHS is ON, SV1(4) keeps OFF.
2) When the AHS is set to be valid for heang mode and DHW mod
e
. In heang mode, AHS control is same as part 1); In
DHW mode, AHS will be turned on automacally when the inial domesc water temperature T5 is too low or the target
domesc water temperature is too high at low ambient temperature. P_o (6) stops running, SV1(4) keeps ON.
3) When the AHS is set to be valid, M1M2 can be set to be valid on the user interface. In heang mode, AHS will be turned
on if MIM2 dry contact closes. This funcon is invalid in DHW mode.
5.1.4 TBH (tank booster heater) control
The TBH funcon is set on the user interface.
1) When the TBH is set to be valid, TBH can be turned on via TANKHEATER funcon on the user interface; In DHW mode,
TBH will be turned on automacally when the inial domesc water temperature T5 is too low or the target domesc
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. TB
H will be turned on if MIM2 dry
contact closes.
5.1.5 Solar energy control
Hydraulic module recognizes solar energy signal by judging Tsolar or receiving SL1SL2 signal from user interface. The
recognion method can be set via SOLAR INPUT on the user interface. Please refer to 8.8.5 "For solar energy input signal"
for wiring.
1) When Tsolar is set to be valid, Solar energy turns ON when Tsolar is high enough, P_s(9) starts running; Solar energy
turn
s OFF when Tsolar is low, P_s (9) stops running.
2) When SL1SL2 control is set to be valid, Solar energy turns ON aer receiving Solar kit signal from user interface, P_s (9)
starts running; Without solar kit signal. Solar energy turns OFF, P_s (9) stops running. The room thermostats are not
connected to the Mono unit but to a motorized valve. Each room’s temperature is regulated by the motorized valve on its
water circuit. Domesc hot water is supp
lied from the domesc hot water tank connected to the Mono unit. A bypass
valve is required.
Part 1 - General Informaon
ROOM THERMOSTAT Control for Space heang or cooling need to be set on the user interface. It can be set in three ways:
MODE SET/ONE ZONE/DOUBLE ZONE. The indoor unit can be connected to a high voltage room thermostat and a low
voltage room thermostat. A hydraulic adapter box can also be connected. Another six thermostats can be connected to the
hydraulic adapter box. Please refer to “ROOM THERMOSTAT in installa
on manual” for wiring.

Space heang
One zone control: the unit ON/OFF is controlled by the room thermostat, cooling or heang mode and outlet water
temperature is set on the user interface. System is ON when any “HL” of all the thermostats closes. When all “HL” open,
system turns OFF.
The circulaon pumps operaon
When the system is ON, which means any “HL” of all the thermostats closes, P_o(6) starts running; When the system is OFF,
which means all “HL” close, P_o (6) stops running.
