EXAMPLE NO. 4 – 5 LOADS, CONTROL MODE - EACH PHASE INDEPENDENTLY
Boiler and pool filtering system specified in example No. 2 plus 2 resistive electric heaters and a heat pump
used to heat the swimming pool. Everything in more complex connection plus control mode set for each phase
separately.
Each electric heater draws 2 kW and should be supplied only with the surplus energy, independently of the
household primary heating system. These heaters must be deactivated at summer time - either through built in
thermostats, by deactivating fuse switches for respective outputs or by deactivating them in the software.
The heat pump draws power of 1.3 kW and it is supplied only with the surplus energy, or manually, outside of
the WATTrouter device.
Connect the following to L1 phase:
- boiler has 1st priority (SSR 1 No. 1), requirements are the same as in example No. 1.
- pool filtering pump has 2nd priority (relay No. 1), requirements are the same as in example No. 2.
Connect the following to L2 phase:
- 1st electric heater with 1st priority (SSR 2).
- heat pump with 2nd priority (relay No. 2).
Connect the following to L3 phase:
- 2nd electric heater with 1st priority (SSR 3).
