menu is as follows and can be scrolled through by 
using the up and down keys:- 
 
SYSTEM PRES X.X: This is current pressure 

reading of system in Bar. This item is non-
adjustable - view only. 

 
COLDFILLPRES X.X: This is the pump cut-out 

pressure in Bar. This is settable from 0.7 to 
3.4. 

 

When moving coldfillpres, cut-in pres and 
low pres alarm will move in line and will 
always keep same differential (e.g. if 
coldfillpres starts at 1.8, cut-in pres at 1.4 
and low pres alarm at 1.2, and then 
coldfillpres was moved to say 2.5, then cut in 
pres would become 2.1 and low pres alarm 
1.9), except when cut-in pres and low pres 
alarm reach their minimum. 

 

When moving coldfillpres upwards, high pres 
alarm will also move upwards, but only once 
0.2 Bar above the current setting (e.g. if 
coldfillpres was moved to 3.1 then high pres 
alarm will automatically become 3.3 if not 
already higher). High pres alarm will not 
move downwards when coldfillpres is moved 
down. 

 
MAKE-UP VO XXXX: This is volume of water 

introduced into system in litres since the unit 
was last reset. 

 

This item is non-adjustable - view only. 

 
MAKE-UP ALARM XX: This is alarm setting of 

volume of water introduced since make-up  
V2 was last reset in 10’s of litres (i.e. 23 
would mean 230 Litres). 

 

This is settable from 1 (10) to 99 (990). 

 

This is used to set off General Alarm to warn 
that the unit has introduced a certain amount 
of water. For instance if set to 23, the alarm 
will go off once the system has introduced 
230 litres of water since make-up V2 was 
last reset and the unit will be frozen and will 
not resume its normal function until make-up 
V2 is reset or make-up alarm is moved 
higher than make-up V2 reading (divided by 
10). 

Note: 

this function can be disabled by 

setting the value to 00. 

 
MAKE-UP V2 XXX.X: This is volume of water 

introduced into system in litres since make-
up V2 was last reset. 

 

By pressing the enter button this will be reset 
to 000.0 

 
PUMP OPS XXXX: This is the total number of 

pump cycles since pump ops was last reset. 

 

By pressing the enter button this will be reset 
to 0000. 

 
PUMP1 HRS XX.XX: This is Pump 1 hours run 

since pump 1 hrs was last reset. 

 

By pressing the enter button this will be reset to 
00:00 

 
PUMP2 HRS XX.XX: This is Pump 2 hours run since 

pump 2 hrs was last reset. 

 

By pressing the enter button this will be reset to 
00:00. 

 
CUT  IN  PRES  X.X:  This  is  Pump  cut-in  pressure  in 

Bar. 

 

This is settable from 0.5 to 3.2. 

 

Cut in pres automatically moves up and down 
when coldfillpres is moved and will always 
keep same differential it had before coldfill pres 
was moved, except when cut in pres reaches 
minimum. 

 

However, cut in pres can be adjusted here. It 
will only go upwards until 0.2 Bar below coldfill 
pres setting. When moving the setting down, 
low pres alarm will automatically move 
downwards once 0.2 Bar below cut in pres. 

 
L PRES ALARM X.X: This is Low Pressure Alarm 

setting in Bar. 

 

This is used to set off Low Pressure Alarm 
Relay to warn that system is below desired 
minimum pressure. 

 

This is settable from 0.0 to 3.0. 

 

Low pres alarm automatically moves up and 
down when coldfill pres is moved and will 
always keep same differential it had before 
coldfill pres was moved, except when low pres 
alarm reaches minimum. Low pres alarm will 
also move down when 0.2 Bar below cut in 
pres, when cut in pres is moved downwards 
and will keep 0.2 Bar difference once this has 
been reached. 

 

However, low pres alarm can be adjusted here 
but can never move higher than 0.2 Bar below 
cut in pres setting. 

 
H PRES ALARM X.X: This is High Pressure Alarm 

setting in Bar. 

 

This is used to set off High Pressure Alarm 
Relay to warn that system is above desired 
maximum pressure. 

 

This is settable from 0.9 to 6.2. 

 

High pres alarm will move up when 0.2 Bar 
above coldfillpres, when coldfillpres is moved 
upwards and will keep 0.2 Bar difference once 
this has been reached. However, high pres 
alarm can be adjusted here but can never 
move lower than 0.2 Bar above coldfillpres 
setting. 

 
PUMP MIN RUN X.X: This is Pump Minimum run 

time in seconds. 

 

This is settable from 1.0 to 9.9. 

 

This function can be used to stop hunting when 
cut in pres and coldfillpres are very close 
together. 

 
PUMP MAX RUN X.X: This is Pump maximum run
