Davey Torrium®2 Controller (TT70/S)

Davey Torrium®2 controller (TT70/S) with Plug and Play lead

APPLICATIONS
Ideal for converting manual pumps to constant flow
water pressure systems. Suits pumps supplying clean,
non-volatile liquids without fibres or solids in such
applications as:-
• Household water supply
• Irrigation
• Water transfer
• Washing systems
• Pressure boosting

1. Constant Flow and Even Water Pressure
   • To prevent annoying fluctuations in water temperature during showers, Torrium®2 uses its intelligence to provide households with constant flow to give even water pressure.
   • It does this with its innovative pressure and flow sensors to start the pump on a pressure drop and to stop it on low flow (~1 lpm). This avoids pump cycling when there is continuing household demand for water.
2. Quick Cut-in for Even Pressure
   • To give you strong pressure right from the start, Torrium®2 is designed to cut in quickly when it senses demand for water. It cuts in when the pressure has dropped to 80% of the previous top (shut-off) pressure.
   • It uses its intelligence to automatically set this cut-in pressure each time the pump stops. In doing so, it allows the system to automatically accommodate for variations in pump performance or site conditions.
3. Adaptive Starting
   • Torrium®2 is clever enough to detect the difference between normal water demand and a small leak in the system, such as a dripping faucet or a leaking cistern.
   • For very low flows, Torrium®2 automatically adapts to reduce the cut-in pressure, which can be as low as 50% of its last shut-off pressure. This significantly reduces pump cycling to improve consumer satisfaction with the system.
   • If normal flow is required in the house (>0.5 lpm), Torrium®2 will sense this and revert to normal mode and initiate an immediate pump start.
4. Easy Status Check
   • To easily check the system status, Torrium®2 has three simple LED indicators:
     • Red LED – the system is in standby mode
     • Green LED – the pump is running
     • Yellow LED – fault condition
5. Pressure Indicator Window
   • Gives a quick guide to the system pressure
   • A colour band of mainly green indicates maximum pressure
   • Mainly red indicates low pressure
   • If the colour band moves slowly towards red this signifies a slow drop in pressure and may indicate a small leak.
6. Greater Hydraulic Performance
   • For better hydraulic performance to supply more pressure with less wasted energy, Torrium®2 has larger water pathways and no moving parts in the pathways. This performance versus loss equation is especially evident at higher flow rates.
7. Greater Reliability
   • To diminish the likelihood of blockages, Torrium®2 is designed with no moving control parts within the water pathways giving greater reliability and performance with varying water quality.
8. Dry Run Protection and Auto Restart
   • To protect the pump from damage due to dry running, Torrium®2 stops the pump when it detects a loss of prime (no water supply) situation.
   • To reduce system downtime, the Torrium®2 waits 5 minutes then goes into auto retry mode, whereby it will restart the pump to see if prime can be re-established automatically.
   • An auto restart occurs at 5 minutes, 30 minutes, 1 hour, 2, 4, 8, 16 and 32 hours.
   • Torrium®2 will also restart if it detects flow through the system (e.g. from mains water pressure returning with pressure boosting applications).
9. Pump Protection – High Water Temperature Cut-out
   • For added security and longer life, a water over-temperature cut-out provides a second level of protection against closed head operation and repetitive cycling.
   • For water temperatures above 70°C Torrium®2 will shut the pump down and the amber LED will be lit. When the water temperature drops to below 60°C, the Torrium®2 will allow the pump to restart.
10. Pump Protection – Excessive Electrical Current
    • To protect the pump motor, Torrium®2 will shut the pump down and indicate a fault if it detects excessive electrical current being drawn. This occurs if the pump motor is subjected to locked rotor or if someone tries to manually override the Torrium®2 by continually holding in the prime button.
11. Corrosion and Scale Resistance
    • To allow Torrium®2 to be used with water of varying quality, its flow sensors are mounted on a high grade stainless steel plate with special anti-scaling electronic action, which only turns the flow sensors on during pump operation.
12. Extra Draw off Capacity
    • To accommodate small leaks and to reduce cycling, Torrium®2 has an in-built spring loaded accumulator for extra draw off capacity. A spring loaded accumulator means low maintenance as there is no need for a pressure vessel with its regular air charging and checking.
    • For increased draw off, an optional pressure tank, up to 18 litres, can be mounted on the vertical outlet.
13. Power Surge Protection for Torrium®2
    • To protect the Torrium®2 controller from electrical surges and spikes, thus extending its life, it has an in-built metal oxide varistor (MOV). The status of the MOV can be checked in the viewing window on the back of the Torrium®2. The MOV is a sacrificial component and should it be consumed due to repeated power surges or spikes, it will almost always blacken the viewing port. This will indicate a non-warrantable Torrium®2 failure.
14. Ease of Installation
    • For ease of installation, the plumbing can be connected to either the vertical or the right angle discharge outlet, which can rotate a full 360°.
