Solar collector control electronics

It can be operated with 5, 12 or 24V power supply, its output is a relay, which e.g. can switch on a pump or electric heating, cooling

Adjustable htemperature range: - Between 40 +125°

Adjustable delay (hysteresis), i.e. e.g. switches off at 60°, but does not switch back on until it decreases e.g. to 55°. This avoids constant switching on and off.

This can also be set in cooling mode, i.e. the relay closes until the room cools down, e.g. to 24°, but does not retract again until e.g. 25°.

DC-: negative input of the power supply

DC +: positive input of the power supply

NC: The relay is closed

NO: The relay is open

COM: Relay common point

Feature description:

P-1: Heating control: If the measured temperature is lower than T1, the relay is short-circuited,
< span style="font-size: 16px; color: #000000;"> Opens above T2

P-2: Cooling control: If the measured temperature is higher than T2, the relay will close if
lower than T1 , then open

P-3: Constant temperature control: If the measured temperature is between T1 and T2, the relay closes, otherwise open

P-4: Constant temperature control:If the measured temperature is between T1 and T2, the relay
opened, otherwise closed

P-5: Setting the delay time

Settings

K1: Press and hold for 2 seconds to function setting or exit function setting; Short press to set upper and lower limits or delay time

In P-1 - P-4 mode: press the K1 button until the display flashes.
Set with the K2, K3 buttons enter the first T1 threshold temperature, then press the K1 button,
then the display flashes again.

Use K2, K3 to set the second threshold temperature T2, then press K1.
In P-5 mode: press the K1 button until the display flashes.

Use K2, K3 to set the first threshold temperature T1, then press K1,
then the display flashes again. Use K2, K3 to set the delay time.

K1 button: selection button

K2 button: plus

K3 button: minus
