WATERHEAT SERIES · WATER/WATER SYSTEM
While heating, the controller begins to heat when the temperature of the temperature sensor is
under "setting temperature – differential temperature", and it stops heating when the
temperature is over "setting temperature + differential temperature"
Water pump delay time
The water pump delay time is set by F21, for example, 3 minutes. The controller contains a
"water pump halt calculagraph", and it begins to time when water pump stops, the program
first check the calculagraph before booting the water pump next time, the program will
immediately boot the water pump if the calculagraph reach 3 minutes.
If the calculagraph doesn't reach 3 minutes, it will boot again when the calculagraph reaches 3
minutes. Thus you can ensure that the boot alternation is over 3 minutes after halt, so it can
prevent to breaking the water pump as a result of frequent boot. In addition, the controller
doesn't boot the water pump within 3 minutes after turning on the power supply, thus the
water pump can also be protected in the state of power cut and then power on.
External alarm
The controller can connect a switching value as external alarm source (Pin 4, 5), when the
external alarm occurs, the controller stops, displays
The alarm code "A11" and generates alarm output. External alarm signal has 5 modes (F50):
· 0: without external alarm
· 1: always open, unlocked
· 2: always open, locked
· 3: always closed, unlocked
· 4: always closed, locked
"Always open" means in normal state, external alarm signal is open, if closed, the controller will
give an alarm; "Always closed" is on the contrary. "Locked" means that when external alarm
signal becomes normal, the controller is still in the alarm state, and it needs to press any key to
resume.
Probation time
A probation time can be set (F87), the controller can add up the running time after power is on,
if the accumulative running time is over the probation time, the controller will stop and display
the alarm code A99, if you want to eliminate the limit of probation time, set the F87 to "OFF",
also you can use the F86 to clear the accumulative running time, and you can try to use it again.
The parameter F85 can be used to examine the accumulative running time of the controller
(hour).
Password
In order to prevent irrespective persons from changing the parameters, you can set a password
(F80), and if you have set a password, the controller will hint you to enter the password after
you press the key "M" for 5 seconds, you must enter the correct password, and then you can
set the parameters. If you don't need the password, you can set F80 to "OFF". Notice that you
must remember the password, and if you forget the password, you cannot enter the set state.
