ART-TEC DTC-1 Temperature Differential Controller (1^oF Hysteresis)

 Designed specifically for photovoltaic (PV) 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 (by 1^oF or more) 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. This typically happens on cold sunny mornings and in the afternoon when the storage tank temperature has peaked and the sun on the collector is dropping. The solar panel will have enough power to continue running the pump long after the collectors have become cooler than the storage tank. At this point flat plate collectors become radiators -- effectively removing heat from your storage tank.

These awesome DTC-1 temperature differential controllers can also be used with outdoor/indoor boilers with radiators, baseboard heaters or radiant heat applications. One sensor is to be placed on the boiler and the second to be placed on the radiator or radiant floor. This way the pump(s) will only operate when the heat source is warmer than the heat load.

Features:

• Pump run indicator  green LED on front panel

• Replaceable 6 amp 3AG type fuse inside

• Built in surge protection

• Under 3mA power consumption (when off)

• Easily Mountable

• Operating Temperature -40^o - 185^oF  (-40^o - 85^oC)

• Measures only 2.5" x 3.5" x 1.25"

Please Note:

  You will need to purchase a pair of thermistors (sensors) below to use with a DTC-1 differential temperature controller.

Any pump can be operated with this DTC-1 temperature differential controller with the use of a relay.

Temperature Sensors for the ART-TEC DTC-1

These are the temperature sensors the DTC-1 uses for a reference temperature. Two thermistors (sensors) are required per DTC-1 controller.

One is mounted to (or inside the collector) and the other is mounted to the storage tank (or floor in a radiant heat application).
