the compressor when to re-start until desired temperature is reached. (3~18°C
(37.4~64.4°F) default: 5°C (37.4°F)). For example, set water temp. = 25°C (77°F), L2 =
5°C (41°F), the compressor will stop at 25°C (77°F) and re-start at 20°C (68°F)
L4-
Desired water temperature limit (30~99°C (86~210.2°F) default: 60°C (140°F))
L5-
allowed electric heating ambient temperature (0~35°C (32~), default: 7°C (44.6°F),
where 0°C (32°F) means no electric heating).
L9-

P3-
allowed discharge temperature (70~135°C (158~275°F), default: 92°C (197.6°F))
P4-
expansion valve opening as four-way valve is defrosting (6~55°C (42.8~), default:

P6-
super heat compensation (0~12 default: 4)
Note: If the controller is chosen with electronic expansion valve not used (the toggle
switch 3 on controller PC Board is on OFF.), it doesn’t display P1-P6 when setting.
4. Clock setting:
