2. Principle of operation
The first function of the regulator is to keep temperature in the water jacket at set value. The
task is realized by measuring temperature (T3) and controlling the throttle (PP) properly. Fireplace
operation temperature is identified by the “
T.Firep
” parameter (see LEVEL PARAMETERS 1).
If fireplace temperature (T3) is higher than the “
T.Firep
” parameter the throttle is gradually shut off
limiting air supply, and if temperature (T3) is lower than the “
T.Firep
” parameter the throttle is
gradually opened up.
The second function is to control the pump (P1) supplying the warm applicable water
accumulator (WAW). The pump operates if fireplace temperature both exceeds the “ON WAW” value
and is higher than the WAW accumulator temperature (T2) by the “DeltaWAW” parameter (see
LEVEL PARAMETERS 1).
The third function is to control the circulating pump (P3) of central heating system. The pump
works if fireplace temperature exceeds the “ON CH” value. It’s possible to activate the WAW priority
function - see the description of operation modes of the pump CH.
The regulator is equipped with the clock to control the WAW priority in selected times of day.
!
The fireplace can also be equipped with warm air distribution system based on the regulator RT-
03C. The regulator measures temperature in the chamber of a fireplace air ventilator and controls its
rotation speed in manual or automatic mode.
