Problem...Tankless Water Heater and Occasional Low Water Pressure

Help! We recently got a tankless water heater. We were really happy with it, until we realized that it seems to freak out when the watter pressure drops low. We are on a well and, when watering the gardens, the water will drop low. When the pressure drops, the heater seems to cycle on and off...on and off... constantly for the duration... even though we are not using hot water. The installers came out and installed a valve(?) of some sort which was supposed to cure the problem. However, this evening is heard it cycling on and off again, even though no hot water was being used. Yikes... seems like it will be 1) hard on the heater 2) using a lot of electricity 3) possibly using a lot of propane to heat. (though I'm not sure the gas is going on and off as well.
Anyone know what we need to have done to cure this???
