Munro BrainBox

Rainwater Harvest Control Box - Standard

Rainwater harvest controls do not have to be so complicated! Using a series of float control switches, the BrainBox monitors the water level in a holding tank. If there is sufficient held water to feed the pump when the start signal is received, the pump will pull the water from the tank. If there is not enough water available, the BrainBox opens an alternate water source – domestic or secondary water supply. This secondary source can be plumbed into the system directly or can be used to maintain a minimum level in the holding tank. Available for use with 110v and 220v line voltage, 
single phase*. 

SPECIFICATIONS

  • Accepts a low amperage start/stop signal – to provide all of the benefits of the standard BrainBox, including loss of prime or run-dry protection, and safe reduced voltage float control, even when signal amperage is reduced
  • Compatible 2-wire system – Works with any brand, any style of 24v lawn controller
  • For use with lawn controllers that provide less than .35 amps for pump start signaling

Sensor and control features

  • A preset pressure sensor alerts the control system of potential pump damage due to loss of prime or run-dry caused by a clogged filter
  • A temperature sensor offers additional protection for pump and pipework in the case of dead head or a solenoid valve not opening
  • Float controls are wired for 24v reduced external voltage, which is safer if people or pets could come in contact with external sensors or switches
  • Provides the pump motor with thermal overload protection, even when the motor itself does not
  • Auto-resets upon cool-down
  • Available 3 hp and above
