Product Details

We are expert in the designing and developing of Solar Differential Controller with perfection. Solar Differential Controller is precisely designed in line with the established quality parameters of the industry. Longer service life, efficient performance and low operating cost are the prominent attributes of Solar Differential Controller. General Descriptions

The DTC-01-A is a differential thermostat for thermal solar systems using a circulator
It is a fully programmable processor
The display shows the temperature in the thermal panel, the temperature in the storage tank and their differences
It has the ability to recognize faults of the sensors, stuck of the circulator and no flow in the circulator loop
The display shows the cause of the faults and the controller activates a sound alarm that informs the user that there is no thermal solar gain
The voice alarm is a necessary operation if the user must avoid energy consumption from other sources (oil or electricity)
Differential controllers without voice alarm will never pay off the cost of the solar system, as in the initial cost will be added the cost of oil or electricity energy, that could be avoided if the user knew the failure of solar energy gain

Technical Data

Housing : White metal box with internal mounting support for extra relay.
Power supply 250 V AC
Outputs relay 10 Am.
Resolution 1 0C
Accuracy +/- 2%
Z slide switch to turn on/off the controller and manual output power.
Î� Button sol-blr-dif. Successive pressing appears the temperature of the thermal panel, the temperature of the storage tank and their differences in the display
A Button Prg-set. Five sec. pressing enters the parameters of the controller

Faults

Fault on the display	S1	S2	Voice alarm
F01	O.K.	Short circuit	Yes
F02	O.K.	Cable cut off	Yes
F03	Short circuit	O.K.	Yes
F04	Cable cut off	O.K.	Yes
F05	Short circuit	Short circuit	Yes
F06	Cable cut off	Short circuit	Yes
F07	Short circuit	Cable cut off	Yes
F08	Cable cut off	Cable cut off	Yes
F09	Very high temp. difference due to circulator stuck or no loop flow		Yes

Basic Operations

Ζ	Slide switch for turning on/off the controller and manual power output
Γ	Button sol-blr-dif. Successive pressing appears on the display the temperature of the solar panel, the temperature of the storage tank and their differences. Wherever you leave the status the display shows the corresponding value.
Α	Prg-set button. Five seconds pressing enters the first parameter of the controller. With the same button you enter the next parameter. Pressing B or Γ button you change the value and you fix it by pressing the Α button. The display flashes twice and returns to the operation status.
