ART•TEC Solar Differential Temperature Controller
DTC-1... Designed specifically for photovoltaic panel powered solar
heating applications, this very basic controller operates from any 12 or 24 Volt PV panel and/or battery
and switches power to a DC circulation pump. It uses 2 standard 10K temperature sensors to sense water
temperatures. If the temperature of the water coming from the solar collector is hotter than the stored
water in the tank it turns on the pump. If the collector is cooler than the tank it turns the pump off.
What could be simpler? The DTC-1 will prevent the loss of stored heat when collector temperatures dip
below the stored water temperature by preventing the pump from circulating cooler water into the storage
tank.
