No. Name Description
Disinfection mode: Is disinfection permitted?
Choice between:
9 Disinfection
Enable – disinfection is permitted
Disable – disinfection is switched off in settings
The setted disinfection temperature (look to: User Menu)
10 Dis. Set. Temp.
The relations between temperature and corresponding time is provided from the Brunette
Resources reference table.
Disinfection time in the risers.
Disinfection time countdown is independent for each riser (look to: User Menu).
Timer is counting when riser temp. is bigger then Dis. Set. Temp.
11 Dis. time [HH:MM]
Minimum required and maximum recommended time depend on the disinfection temperature
and should be selected from the Brunett Resources reference table.
Dividing risers into groups
If dividing is Enable, system is counting progress of disinfection of active risers, between divide
12 Min. divide adv. (%) time period. If in divide time period progress of disinfection is less than Min. divide, adv. active
risers will be automatical divided to half. New active group will continue with most promising
(hottest) risers.
Group division period
If dividing is Enable, Controller will calculate the average disinfection progress of active risers,
between Divide time period. If in divide time period progress of disinfection is less than Min.
13 Divide time
divide adv. Active risers will be automatical divided to half. New active group will continue with
most promising (hottest) risers.
Factory setting: 20 min
Electronically controlled circulation temperature after disinfection in riser. Controller can maintain
the requested circulation temperature in the riser after the disinfection process. This function is
14 Circ. Set Temp. recommended for control valves with only actuators (PI control signal). For self - acting valves like
MTCV (with basic thermostat element) recommended setting is 5 °C.
Factory setting: 5°C
Outputs status:
15 O1-heat force Open – when disinfection is not active
Close – when disinfection is in progress
Outputs status:
16 O2-start next Open – when disinfection is not in progress or not finish
Close – when disinfection is finished in sequence mode
17 Disinfection Disinfection process is enabled or disabled. (can be changed in User menu->Disinfection)
18 Total Dis.Adv Advance of Disinfection progress, calculated from all (active and non active) risers.
19 Dis. timeout Time to finish
Advance of Disinfection progress, calculated from active risers. After divide time period, Divide
20 Divide adv. adv. Is compared to Min.Divide adv. If Divide adv. is less than Min.Divide adv. risers will be divided
to half.
21 Divide timeout Time left to compare Divide adv. and Min.Divide adv. to make decision about divide risers.
Number of risers in the currently disinfected group.
If no division was made, this is the total number of risers. Option of choice divides risers into
22 Ris. in group
groups during disinfection or is used in Installer Menu. Function: To be used division enables
disinfection process to accelerate in extensive hot water circulation installations.
Outputs status:
Open – O3 is closed to common (C)
23 O3-dis. finished
Close – shortcut to common (C)
Outputs status:
Open – O4 is closed to common (C)
24 O4-alarm
Close – shortcut to common (C)
Order number of risers (look to: Installer Menu)
Number of riser in risers status section
Open - no sensor or break sensor circuit
Closed – shortcut to ground in sensor circuit
25 Riser
Riser statuses are indicated with color.
- White: non relevant (disabled in Installer->risers number) risers
- Red: Disinfection in process, all temperature is OK
- Blue: Disinfection in process but riser temperature is lower than Dis.Set.Temp
- Yellow: if Sn temp. sensor or cable is broken
Status of valve: V1 ... V36
26 Valve output 1 – valve is open in % shown in Valve [%] column.
0 – valve is closed Valve [% ] = 0%. Status 1 is shown when valve open ratio is more than 0%.
27 Valve [%] % of opening of valve (V1 ... V36) in PWM mode
Temperature readings in riser
Sensor S1,.., S36 temperature
28 Temperature [°C]
Open - no sensor or break sensor circuit
Closed – shortcut to ground in sensor circuit
Place in ranking of disinfection progress of risers (at dividing period system will continue
29 InGroup
disinfection with best ranking risers)
% of riser disinfection progress
30 Disinfection
Count down timer is counting when temp. on riser is higher that Dis.Set.Temp.
31 Time to end [HH:MM]
After timer count down to zero, riser is disinfected successfully.
