General instructions
This supplementary sheet is an addition to the Softmaster
®
ROE 2 operating instructions. It only contains the
additional functions or modifications of the special version Softmaster
®
ROE 2 S5. This supplementary sheet is only
valid in combination with the standard Softmaster
®
ROE 2 operating instructions.
When using the remote maintenance software “Heyl Remote Contol”, please observe that the software only covers
the standard functions of the ROE 2.
Description
The processing and programming of the low water message has been modified according to the following
description. Please refer to the Softmaster
®
ROE 2 operating instructions for further information.
LP Low water pressure (terminals “LP” / 33, 34)
Connection for volt-free pressure switch
Install a pressure switch in front of the pump in order to protect the pressure pump. A serial or parallel connection of
two pressure switches is also possible. If the pressure switch switches, the plant is switched off after a programmable
test time. The fault is displayed with the red LED "Error message" and on the display. A continuous alarm occurs at
output "Alarm" and an entry in the error list takes place.

- Immediate alarm for first message
Not programmable:
- System switch off
- Continuous alarm after switch off
- Entry in the error list
It is possible to program the reaction of the controller during low water. Determine how often the plant is to be
restarted. A restart occurs between 1 and 99 minutes depending on the programming. If the water is still too low, the
plant is once again switched off after the test time and until the number of restarts has been reached. If you wish to
generate an error message for the first low water message irrespective of the number of restarts attempts, select
“Immediate alarm” in the last menu option. This does not stop the further restart attempts.
The following options activate output alarm “AL”:
- the maximum number of restarts has been reached
or
- “Immediate alarm” in the menu is setting
An entry in the error list occurs in both cases.

Programming
Function Low water pressure , Input low water pressure monitoring LP
"M" º BASIC PROGRAM º Fct.Low w.press
Normally closed/normally open
Program the desired effect of the connected contact for low pressure monitoring,
normally closed or normally open.
Delay LP
Delay time in seconds after which an alarm is triggered and/or the plant should be
switched off if the water/pressure is low.
Restart
Program how often the plant is to be switched on again after the switch off caused by
low water pressure.
The plant can be re-started up to 9 times until the final switch off.
Interval
Select a restart interval of between 1 and 99 minutes.
Immediate alarm
Select “Immediate alarm” if you wish to generate an error message for the first low water message irrespective of the
number of restart attempts.
Error message “Low water pressure“
The pressure switch in front of the pressure pump for the dry-running
protection has triggered.
The plant has been switched off after the programmed delay time (Delay LP). Restart the plant with the "RUN/STOP"
key. If water is still low, the plant is switched off again after the delay time.
If the system has been switched off via the dry-runnig switch, automatic control of storage tank refilling results in a
system restart after a programmable time from period of between 1 and 99 minutes. This time period can be
programmed under “Programming/Function low water pressure”.
Program the number of restart attempts after low water pressure under “Switch on” in menu “Funct. low water
pressure”.
Confirm the fault display with the “Alarm” key.
The error display is only deleted after the fault has been eliminated.
