Torrium® Description
The Torrium® can automatically adapt to changing conditions because it has an in-built titanium mounted brain that can out-smart every-day problems. The Torrium is easy to install, needs no adjustment and has few maintenance issues. It's unique ability to respond to changing circumstances ensures a steady, reliable flow of water - and is virtually guaranteed day after day, year after year.
The Torrium® measures the pump shut off head each time the pump stops, and sets the cut-in pressure at 80% of shut-off head, so that the consumer is unlikely to notice any pressure change when the pump is switched on.
The Torrium® adapts each time the pump stops, thus allowing the system to accommodate variations in pump performance or site conditions.
The Torrium® starts pump on pressure drop and stops pump on low flow (~0.5 GPM), thus reducing pump cycling for constant and even water pressure.
The Torrium ® controller has an in-built accumulator which will accommodate small leaks. In some applications it may be appropriate to install an additional accumulator (Supercell pressure tank or equivalent). These applications include:
- Long suction lines
- Low flow appliances connected to the pump, such as evaporative air conditioners (humidifiers), ice makers, RO systems or slow filling toilet cisterns.
Features:
- CONSTANT FLOW
- LOSS OF PRIME PROTECTION
- ADAPTIVE PRESSURE SWITCH
- SIMPLIFIED FAULT FINDING
- AUTO RETRY
Explanation of Features and Operation
The Torrium® has a simple indicator and fault LED system. Red constant means that the system is in standby. Green constant means the pump is running.
Cistern Fill mode is activated when The Torrium® detects frequent short cycling, such as may be encountered with a very slow filling toilet cistern. The Torrium® will then ensure the pump continues to operate for at least 2 minutes.
The Torrium® stops the pump in loss of prime circumstances and activates the "loss of prime" LED indicator sequence (red LED single flash per sequence), thus protecting the pump from dry run damage and helping to identify installation faults.
When the Torrium® detects loss of prime, it waits 5 minutes, then goes into auto retry mode, whereby it will restart the pump to see if prime can be re-established automatically. Auto retry occurs at 5 minutes, 1 hour, 2, 4, 8, 16, and 32 hours.
If The Torrium® detects excessive electrical current, such as when the pump motor is subjected to locked rotor or when someone tries to manually override the Torrium® by holding in the prime button, the Torrium® will shut the pump down and indicate 2 red flashes per sequence.
Should the Torrium® detect low incoming voltage (below 90 volts for 115V model and below 180 volts for 220V model) it will allow the pump to continue to operate if possible, but it will flash two red flashes per sequence over the green run LED.
Water over-temperature cut-out fail safe protection provides a second level of protection against loss of prime and/or closed head operation and/or repetitive cycling for added security and longer life. If the Torrium® detects water temperature above 158 degrees F it will shut down the pump and flash 3 red LED flashes per sequence. Once the water temperature has dropped to below 140 degrees F, The Torrium® will allow the pump to restart.
The Torrium® also detects slow leaks and attempts to overcome the short run times such leaks can cause by dropping temporarily the cut-in pressure to 50% of the last shut-off head. The Torrium® will return to 80% cut-in pressure after 100 cycles or if a manual reset is initiated.
