Description:

Digital Differential Thermostat for your solar project. Want to build a solar hot water system yourself? Want to recover the heat from you attic in the winter?You can use one of these to trip the pump on my solar hot water collectors, but they can do more than that. This will work perfectly to turn your pumps or fans on and off. Note that this is a thermostat and not a motor controller, you should use a proper relay or contactor, and control that with this thermostat. Two temperature sensors are provided with this item. They are linear active temperature sensors that have been cased and potted, with short pieces of wire attached so you can extend them for your project. Specifications: Working Voltage: AC220V 10%(50Hz/60Hz) Output Load: 5A/220V/AC Power Consumption: 3W Heating Control Range: 299 Temp. Difference Start Control: 350 Resolution: 1 Precision: 1 Input Signal: 2-channel sensor, 20KX1. 5MX2 Size: 76*76*35mm/2. 99*2. 99*1. 37in Operating Temperature: -1050 Operating Humidity: RH90% Light Function Setting Range Default Unit #1 temperature difference start stop pump temperature difference +150 5 #1, #2 stop pump temperature difference 1temperature difference start-1 2 #2 temperature return difference 120 5 #3 high temperature correction -1010 0 #4 low temperature correction -1010 0 Package Includes: 1 x Temperature Controller 2 x Sensor Probes Features: The products are used in solar water heater, the temperature difference and temperature to control the output It is provided with two output control, temperature difference control two temperature zone When the temperature reaches the set value, it automatically runs the water pump circulation and makes the two temperature zone temperature equilibrium The other channel controls electric heating, when the solar heating failed to reach the set temperature, the electric heating system can automatically start and heat to the set temperature It will control heating system and automatically makes water temperature stay in temperature deference range.
