8.2.4 Boiler temperature control

The Remeha Quinta 115 has electronic temperature control with flow and return

temperature sensors. The flow temperature can be adjusted between 20 and 90°C.

8.2.5 High limit temperature protection

The high limit temperature protection device switches off and locks out the boiler when

the flow temperature exceeds the high limit set point (adjustable). When the fault is

corrected, the boiler can be restarted by using the 'reset'-key on the control panel.

8.2.6 Low-water protection (flow and content)

The Remeha Quinta 115 is supplied with a low-water protection on the basis of

temperature measurement, see Fig. 22, Boiler sensor resistance/temp graph. By

modulating back at the moment that the water flow threatens to fall too low, the boiler

is kept operating for as long as possible. In the event of low flow (F/R dT = 45°C), the

boiler will shut off and not lockout (ref. Par. 6.4).

If the boiler is fired dry, it will go to high temperature lock out, failure code 1*

8.3 External connections

All external connections are made on the 24 way terminal strip, located in the

instrument box at the bottom of the boiler, accessed by loosening the two screws, see

Fig. 13 and Fig. 14.
