Jaga - Heating with 6 zones

Use case

Your customer has one of the following Jaga radiator systems with 6 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:

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.

Create the thermostats (THT1 to THT6).
Create the zone valves (VALVE1 to VALVE6).
Create a heating system (H/C1).
Create the digital sensors (SENS1 to SENS6) for heating requirement.
Create the other switched devices (OUT1 to OUT6) for controlling the 230 V to the zone valves.
Create the analogue outputs (OUT7 to OUT12) for controlling the fans.

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.

In Z1,

Create a routine Scene (ROUT2) to define the ventilation speed "low". Use the following behaviour:
1. Select the device that is part of the routine : analogue output OUT7
2. Set the parameter level to 30%
Create a routine Scene (ROUT3) to define the ventilation speed "medium". Use the following behaviour:
1. Select the device that is part of the routine: analogue output OUT7
2. Set the parameter level to 60%
Create a routine Scene (ROUT4) to define the ventilation speed "high". Use the following behaviour:
1. Select the device that is part of the routine: analogue output OUT7
2. 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:
1. Device that is part of the routine: analogue output OUT7
2. Start behaviour: OUT7: Level = On, Dimming Time = 1 s, Delay = 0 s
3. Stop behaviour: OUT7: Level = 60%, Dimming Time = 1 s, Delay = 0 s
4. Check "Stop this routine automatically..." and set the time period to 15 min

In Z2 to Z6 follow the steps described above but use the data in the table below.

Type of routine	In Z2	In Z3	In Z4	In Z5	In Z6
Scene	ROUT6, ROUT7 and ROUT8 with OUT8	ROUT10, ROUT11 and ROUT12 with OUT9	ROUT14, ROUT15 and ROUT16 with OUT10	ROUT18, ROUT19 and ROUT20 with OUT11	ROUT22, ROUT23 and ROUT24 with OUT12
Custom routine	ROUT9 with OUT8	ROUT13 with OUT9	ROUT17 with OUT10	ROUT21 with OUT11	ROUT25 with OUT12

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
OUT7: Level = Unlock, Delay = 0 s
OUT7: Level = 60%, Dimming Time = 1 s, Delay = 0,1 s
ELSE
OUT1: Value = Off, Delay = 0s
OUT7: Level = Off, Dimming Time = 1 s, Delay = 0 s
OUT7: Level = Lock, Delay = 0,1 s

In Z2 to Z6 follow the steps described above but use the data in the table below.

In Z2	In Z3	In Z4	In Z5	In Z6
COND2 with SENS2, OUT2 and OUT8	COND3 with SENS3, OUT3 and OUT9	COND4 with SENS4, OUT4 and OUT10	COND5 with SENS5, OUT5 and OUT11	COND6 with SENS6, OUT6 and OUT12

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)	the zone valves VALVE1 to VALVE4 (contact 1 to 4 of the module). the heating system H/C1 (contact 5 of the module) () (*).
a heating or cooling module 4U (MOD2)	the zone valves VALVE5 and VALVE6.
a digital sensor module 2U (MOD3)	the digital sensors SENS1 to SENS3.
a digital sensor module 2U (MOD4)	the digital sensors SENS4 to SENS6.
an analogue control module 0 - 10 V 2U (MOD5)	the analog outputs OUT7 to OUT9.
an analogue control module 0 - 10 V 2U (MOD6)	the analog outputs OUT10 to OUT12.
rail coupler (MOD7)	/
a switching module (6x) 4U (MOD8)	the other switched devices OUT1 to OUT6.

(*) This contact is not physically used in the installation.

(**) The contact closes when one of the thermostats demands heating.
