INTEGRAL
Integral is a program to set the startup time and distance between compressor and electrical heater, to set
stop conditions of compressor and electrical heater. This program is depends on the "feed water temperature
degeneratiaon" and Time.
COMPRESSOR A
ADD1
TIMESETTING
To set Time, year, month, date, and week; electrical heater timing, water tank heating timing, whole unit timing.
SETTING
To set Emergency mode 1, Emergency mode 2, night mode, day mode, start conditions of electrical heater.
OPER.TIME
To calculate how much time have been running by compressor, electrical heater.
RESET
Return to factory settings: press button Right to go back all factory settings.
MAN TEST
Engineer testing
Sub-Menu OPERATION
WARMWATER
Water tank heating( warmwater) mode: when enter this mode( under this mode has a program call
compressor restart determined by water temperature degeneration'), heat pump only heat the water tank.
The unit stops running as soon as water tank's temperature gets to setting temperature, then compressor
restart determined by water tank temperature degeneration( CMPDIF TEMP)
ROOMHEAT
Room heating mode: when enter this mode, heat pump only heat the room. In this mode heat pump runs
according to the relationship between Time and Feed water temperature, under a constant ambient
temperature, operator can change the feed water temperature through slope of the CURVE.
ROOMHEAT1
Room heating mode 1: when enter this mode, heat pump only heat the room. In this mode heat pump runs
according to Feed water temperature, operator can set the feed water temperature directly
(adjustable from 20 to 65 , factory setting is 45 )
ROOMHEAT2
Room heating mode 2: when enter this mode, heat pump only heat the room. In this mode heat pump runs
according to room air temperature, operator can set the room air temperature directly (adjustable from 16 to
31 , factory setting is 27 )
WARMWATER+ROOMHEAT ROOMHEAT1 or ROOMHEAT2
Auto mode: select ( ) water tank heating and room heating at the same time, enter Auto mode. After enter
this mode, water tank heating has the priority (compressor restart when in water tank heating must follow
program 'CMPDIF TEMP'). When water tank get to setting temperature, three -way valve will change its
direction to room heating or cooling automatically. If the water tank temperature decrease, three-way
valve's direction
will go back to water tank heating.
