System:

Holiday function

The holiday function is used for operating the system when no water consumption is expected, e. g.

during a holiday absence. This function cools down the system in order to reduce the thermal

load.When bottom temperature of tank below down 35oC,the solar pump is deactivate.Manual of SR208C intelligent controller

Activate/deactivate this function:

►Press “ ” button for 3 seconds, “HDAY 05” displays on the screen

►Press “▲/▼”, to adjust holiday’s days, adjustable range 0-99 days

►Press “ ” for 3 seconds again, to adjust holiday’s days to 0,

►Press “ESC” to exit, holiday function is closed

Note:When you return from holiday, please deactivate this function in time.

WIFI Remote Control is available for SR208C WIFI only.

SR208C

SR208C Solar Controller Water Heater Controller for split solar system.

1 pt1000 and 2 ntc10k temperature

2 years warranty

Working Principle

1 collector array.

1 storage tank.

1 pump and auxiliary heating.

Description: The solar circuit pump (R1) is switched on as soon as the switch-on temperature difference (Delta Ton) between the collector array (T1) and the storage tank (T2) is reached.

If the temperature difference between the collector array (T1) and storage tank (T2) drops below the switch-off temperature difference (Delta T off), or the temperature of storage tank (T3) reaches the preset maximum storage temperature, then the solar circuit pump ( R1) is switched off.

Back-up heating by auxiliary boiler Within the preset time section of back-up heating, if the temperature T3 is below the switch-on temperature, then the circulation pump ( H1) of back-up heating is triggered, when T3 is heated to the switch-off temperature, circulation pump H1 of back-up heating is ceased.
