Checking; Failure; Winter Storage; Restart - PSA ZODIAC Uranus+ Manual De Instalación Y De Uso

With a demand for heating and the filtering in operation, the "reg" led flashes for 15 seconds, then stays
on. The internal regulator contact (terminals 19-20) is then closed => heating in progress (the circulator
must be in operation).
N.B.: energy is transferred to the secondary circuit to give calories to the pool.
Observation:
- when the appliance heats the water ("reg" led lit up), if the filter stops or if the water flow rate is less than 1,1
m³/h, the appliance stops heating ("reg" led flashing). The flow controller "CD" is open,
- when the pool reaches the desired temperature, the appliance stops heating ("reg" led off).

6.3 Checking

Make sure that the heat exchanger stops when:
• decreasing the required temperature on the control thermostat,
• filtration is switched off or closing a valve 2 or 3 on the by-pass,
• when pressing key
Important! Before any intervention, make sure the unit is switched off.

6.4 Failure

• if the regulation probe is out of service or disconnected, with a flashing "E0" displayed, appliance
switched off and disabled, reconnect or change the probe.
• If the regulator display does not work, check that:
1) the mains supply is live,
2) the regulator protection fuse is not blown (see paragraph 5.3)
• if the pool water temperature rises beyond the setpoint temperature, check that:
1) the regulator is working properly,
2) no other circulator is pushing on the primary circuit. If this is so, plan for a solenoid valve at the
outgoing direction of the primary heating circuit controlled by terminals 19-20.

6.5 Winter storage

• switch off the appliance by pressing key
• switch off the power supply (by disengaging of the 30 mA differential circuit breaker at the head of
the exchanger line),
• drain the pool circuit by removing both connection union fittings in order to avoid the risk of frost.
• drain the primary circuit by removing the drain plug if frost can be expected.
The guarantee will be cancelled in event of frost of the appliance due to an improper

6.6 Restart

• refer to the procedures described in paragraphs 6.1, 6.2, 6.3 and 6.7.
6.7 Maintenance
To be done once a year by an approved and qualified person:
• visual check of the condition of the various electrical components.

7. WARNING

Make sure the appliance is disconnected from mains supply before any intervention.
Any intervention shall be performed by qualified and authorised personnel only.
