The DT-H5RO-I controller is designed to operate a filter pump when filtration is called for by either the chlorinator or heater.

Heat Demand
As most pools are filtered for 8 hours a day, extra run times are often required to maintain the water at the desired temperature. The heat pump/gas heater is equipped with a ‘Demand Heat” function that will assist in maintaining the temperature of the pool by communicating to the H5R0-I. The controller will over-ride the filter pump when heat is called for by the heat pump which monitors the temperature within its defined run times. By this mean, the user is sure the water is always ready to bathe, day or night.
