I have Hayward Easy Temp heat pump for my pool.  The Easy Temp has a flow sensor that shuts down the fan and the compressor when it senses that there is no or low water flow to the unit.  I have a timer in line with the power supply to my pool pump that will allow me to have my pump operational during pre-selected periods.  My question is this:  will it be harmfull to my heat pump to keep it powered up 24x7 and utilize the interal flow sensor to secure the fan/compressor or will this be harmfull to the heat pump which would requre me to run the pool pump 24x7 (which I will not do) or manually go out and turn on and off the pool pump and the heat pump?
