Control function
Note:
1. Min. space heating/cooling operation time of [Space_HP_tmin] will be limited to 20 minutes to accelerate shift of DHW
operation When DHW schedule priority is activated at specic setting Starting Time, DHW boost is activated (referring to
10.3.6), or DHW Anti-legionella is activated (referring to 10.3.5).
The conguration of this option should be done through the master controller.

(3) DHW set temperature priority
Set Hysteresis between DHW set temperature and DHW temperature as [DHW Setting Temperature Di󰀨erential Temp] to
start DHW operation shift.

Alternate operation between Space heating/cooling and DHW
.
● Meet all following conditions to start DHW operation shift (DHW Switch ON).
(1) TDHW ≤ TDHWS - DHWS_shift_di󰀨 or TDHW1 ≤ TDHWS- DHWS_shift_di󰀨 if TDHW1 is valid.
(2) Period time of space heating/cooling operation shift is more than [Space_HP_tmin] or space heating/cooling has no
demand.
● Meet one of following conditions to start space heating/cooling operation shift (space heating/coolingSwitch ON).
(1) TDHW is met and TDHW1 is met if TDHW1 is valid.
(2) Max temperature of THPSTOP is reached. (THPSTOP refers to 10.3.4).
(3) Period time of DHW operation shift is more than [DHW_HP_tmax].
