Picture 1. Front plate of the RK-2001W controller
Basic operation of the controller is carried out by setting the desired temperature
with boiler thermostat knob, other functions are carried out according to parameters
programmed in service mode. The change in the boiler temperature setting is
displayed on the display for a few seconds, e.g.
[C 80]
and this value means the
temperature of the water in the boiler which the controller will be trying to achieve. You
can also check this value by pressing OK button for a short time. After pressing
START button the fan starts to work and the control process begins. STOP button
stops the fan for example to add fuel.
If the controller is not in user or service mode the display shows water temperature
in the boiler and the last character on the display defines the mode which the
controller is currently in:
for example:
[50º-] - STOP mode
[50ºC] - WORK mode
[50ºc] - hold up of burning in WORK mode
[50ºU] – heating of hot water in SUMMER mode
[70ºd] – total bacteria control – heating up of hot water
up to 75ºC.
4. Setting up the user parameters.
Holding OK button enters the user mode and allows to review and is indicated by
fast flashing of the room thermostat indicator. You can look through the parameters
with < and > arrow buttons. After choosing the desired parameter you can switch to
the change mode of the parameter by pressing OK button - it is indicated by the value
of the parameter flashing.
Change of the parameter is done by pressing - or + buttons. You can confirm new
settings by pressing OK button and after that the controller allows to choose another
parameter (with < > buttons). If you do not want to change the parameter value with
the < or > button choose [End] and press OK or wait for 1 minute – the controller will
exit the service mode and will indicate the temperature of the water in the boiler
CAUTION:
If in the controller the hot water pump is turned off in the user menu. After
pressing OK, you can only read the set temperature value of the boiler thermostat.
