7.6.5 Submenu - REC    Tank recooling temperature   

Description: 

If temperature of first tank is over its maximum temperature, and at the same time, collector 

temperature is minimum 5

o

C lower than tank temperature, then solar pump is triggered, 

through this reversed circulation, tank temperature is reduced by heat loss occurs in collector,   

solar pump keeps working until tank temperature drops below its maximum temperature. 

 

Setup steps: 

To access main menu TEMP, then select submen

u REC, “REC OFF” displays on screen, 

default set is off. 

►Press “SET” button, parameter “OFF” blinks on screen 

►Repress “SET” button to activate or deactivate this 

function, after function activated; factory set is “REC ON” 

► Press “ESC” button to exit the menu or wait for 20 

seconds to exit ,, parameters are saved automatically. 

 

REC signal displays on screen, it indicates this function is activated. 

 

7.6.6 Submenu - SMX1 Maximum temperature of tank   

Description: 

When the DT between collector T1 and Tank( T2) caters the switch-on DT of circulation, solar 

pump is triggered, but in order to avoid the high temperature inside tank, controller    checks 

whether the temperature (T3) in top of tank    is higher than maximum temperature of tank, 

when T3 is higher than preset SMX temperature, solar pump is ceased even at the case that 

DT  caters  condition. When  tank    temperature  T3  drops  and  is  2

o

C  below  the  SMX,  solar 

pump restarts when DT caters condition. 

 

Setup steps: 

To access main menu TEMP, then select submenu SMX1, “SMX 1 60

o

C” displays on screen. 

►Press “SET” button, parameter “60

”blinks 

►Repress “SET” button to activate and deactivate this 

function, if function deactivated, “SMX1 - - -” displays on 

the screen.
