Setting of water-glycol-mixtures  
for zelsius C5 „Glycol Meter“

Selection of the display „E 0“ 
on Level 1
 
Press the button for about 2 
seconds until letter „E“ flashes
 
With each short press on the 
button the following loop for dif-
ferent mixing ratios runs:  

E 20 - E 25 - E 30 - E 35 - E 40 - E 45 - E 50
P 20 - P 25 - P 30 - P 35 - P 40 - P 45 - P 50 - E 0

E   = ethylene glycol  
P   = propylene glycol
E  0 = water without glycol additive
 
Upon reaching the required value, press the but-
ton for about 2 seconds to program the value. 
Buchstabe  Letter  "E"  or  "P"  will  stop  flashing. 
The programming process can be retried if nec-
essary.
