CCR3+ Controller
ENGLISH
READINGS MENU:
No. Name Description
1 O1..O4
Output status (Defined output O1..O4)
Open - no alarm or break alarm circuit
Closed – shortcut to ground in alarm circuit
See Outputs settings in Installer Menu.
2 B1..B3
Input status
Open - input Bx open
Closed – input B1 close to G
Free contact relay (not used in CCR3+ process, only for monitoring in BMS). Binary inputs or PT1000
sensor (5V, 1mA).
3 RT Clock
The Real Time clock, show current time, date, day of the week.
Data used in archive file.
4 S0-main temp.
S0 – value of (°C) supply temperature. The same readings apply to sensors S1 … S20.
Open - no sensor or break sensor circuit
Closed – shortcut to ground in sensor circuit
Fault – temp. values exeed Fault temp. max or is bellow Fault temp. max (correspondent to Fault temp.
settings in Installer Menu)
5 Ret.Set.Temp
Information about setting return temperature correspondent to current flow temperature, in °C degree.
Required range set in points in the Installer Menu. Function used for temperature alarm output.
Set. Temperature is = Return Set. Tempe/- Shift T. Set.
6 Alerts
General information about CCR3+ status
OK – system is running without alarms
Alert (red) – system has alarms
Riser Status (sensors: S1-S36; valves: V1-V36)
7 Riser
Number of risers (look to: Advanced Menu)
Riser statuses are indicated with color.
OK – riser status is OK
High (red) - if temp. on Sx sensor is higher then Ret.Set.Temp
Low (blue) - if temp. on Sx sensor is lower then Ret.Set.Temp.
Open (yellow) - no sensor or break sensor circuit
Closed (grey) - shortcut to ground in sensor circuit
N/A (white) - non relevant (non selected) risers
8 Valve output
Status of valve: V1 … V36
1 – open, valve output closed to C (powered up), (taking PWM into account).
0 – valve closed, valve output closed to C (powered down), (taking PWM into account).
Valve is 1-Open if: PWM min < Valve % <PWM max
9 Valve [%] … ..% – valve open ratio – percentage of filling the PWM function (0 … 100 % in 10 % steps)
10
Temperature
[°C]
Temperature readings in riser
Open - no sensor or break sensor circuit
Closed – shortcut to ground in sensor circuit
11 Set. Temp.[°C]
Information about return temperature correspondent to Ret.Set.Temp and Shift setting (correspondent
to Shift T.Set in Shifting Menu)
Set. Temperature is = Return Set.
Tempe/- Shift T. Set.
12 Alerts
Temperatures status (same color as described in pos. “Riser status”):
Riser RX – riser status information:
OK – riser status is OK
High (red) - if temp. on Sx sensor is higher then Ret.Set.Temp
Low (blue) - if temp. on Sx sensor is lower then Ret.Set.Temp.
Open (yellow) - no sensor or break sensor circuit
Closed (grey) - shortcut to ground in sensor circuit
N/A (white) - non relevant (non configurated) risers
