System:

Holiday functionThe 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 thermalload.When bottom temperature of tank below down 35oC,the solar pump is deactivate.Manual of SR208C intelligent controllerActivate/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 closedNote：When you return from holiday, please deactivate this function in time.
