Jaga - Heating with 4 zones
Use case
Your customer has one of the following Jaga radiator systems with 4 zones:
a Strada Hybrid or Clima Canal equipped with a Jaga Dynamic Product Controller or
a Briza
Each zone is equipped with a zone valve controlled by a thermostat.
When heating is required, your customer wants to control the speed of the ventilators mounted on the radiators with the Niko Home app:
low (30%)
medium (60%)
high (100%)
boost (100% for 15 min)
When no heating is required, your customer cannot activate the ventilators.
You can also use push buttons with LED(s) and comfort sensors instead of thermostats, or a combination of both.
Procedure
Creating the controls and the devices
Create the thermostats (THT1 to THT4).
Create the zone valves (VALVE1 to VALVE4).
Create a heating system (H/C1).
Create the digital sensors (SENS1 to SENS4) for heating requirement.
Create the other switched devices (OUT1 to OUT4) for controlling the 230 V to the zone valves.
Create the analogue outputs (OUT5 to OUT8) for controlling the fans.
Creating the routine
Create a routine Heating/cooling per circuit (ROUT1). Use the following behaviour:
Select the heating system (H/C1).
Define the heating zones. Combine the correct thermostat with the corresponding zone valve (THT1 and VALVE1, THT2 and VALVE2, ...).
(optional) Create notifications.
Creating the routines
In Z1,
Create a routine Scene (ROUT2) to define the ventilation speed "low". Use the following behaviour:
Select the device that is part of the routine: analogue output OUT5
Set the parameter level to 30%
Create a routine Scene (ROUT3) to define the ventilation speed "medium". Use the following behaviour:
Select the device that is part of the routine: analogue output OUT5
Set the parameter level to 60%
Create a routine Scene (ROUT4) to define the ventilation speed "high". Use the following behaviour:
Select the device that is part of the routine: analogue output OUT5
Set the parameter level to On
Create a routine Custom routine (ROUT5) to define the ventilation speed "boost". After 15 min the ventilation is set to "medium". Use the following behaviour:
Device that is part of the routine: analogue output OUT5
Start behaviour: OUT5: Level = on, Dimming Time = 1 s, Delay = 0 s
Stop behaviour: OUT5: Level = 60%, Dimming Time = 1 s, Delay = 0 s
Check "Stop this routine automatically..." and set the time period to 15 min
Create the conditions
If heating is required in a zone, then 230 V is applied to the zone valve, the fans are unlocked and the ventilation speed is set to 60%.
If heating is no longer required in a zone, then 230 V is no longer applied to the zone valve, and the fans are locked and stopped.
In Z1, create a condition (COND1) for controlling the fans. Use the following logic:
IF SENS1 = True
THEN
OUT1: Value = On, Delay = 0s
OUT5: Level = Unlock, Delay = 0 s
OUT5: Level = 60%, Dimming Time = 1 s, Delay = 0,1 sELSE
OUT1: Value = Off, Delay = 0s
OUT5: Level = Off, Dimming Time = 1 s, Delay = 0 s
OUT5: Level = Lock, Delay = 0,1 s
In Z2, Z3 and Z4 follow the steps described above but use the data in the table below.
In Z2 | In Z3 | In Z4 |
|---|---|---|
COND2 with SENS2, OUT2 and OUT6 | COND3 with SENS3, OUT3 and OUT7 | COND4 with SENS4, OUT4 and OUT8 |
Filling the cabinet and addressing the devices
You can only address four zone valves to a heating or cooling module 4U. Contact 5 of the module is an H/C-contact.
Always address the heating system to the first heating or cooling module in the cabinet (contact 5).
Fill the cabinet with ... | and address the following devices ... |
|---|---|
a heating or cooling module 4U (MOD1) |
|
a digital sensor module 2U (MOD2) | the digital sensors SENS1 to SENS3. |
a digital sensor module 2U (MOD3) | the digital sensor SENS4. |
an analogue control module 0 - 10 V 2U (MOD4) | the analog outputs OUT5 to OUT7. |
an analogue control module 0 - 10 V 2U (MOD5) | the analog output OUT8. |
a switching module (6x) 4U (MOD6) | the other switched devices OUT1 to OUT4. |
(*) This contact is not physically used in the installation.
(**) The contact closes when one of the thermostats demands heating.
