REMEHA QUINTA RANGE
9
General
The Remeha Quinta Range is supplied as
standard with electronic control and flame
ionisation safety controls, with a specially
designed microprocessor at the heart of the
control system.
Specifications
Electrical supply
The Remeha Quinta Range must have a
permanent 230V-50Hz single phase supply rated
at 6.3 amps. The control unit is not phase
/neutral sensitive.

Fuse specification
The boiler is protected by fuses:
- on the main power supply located in the euro
connector socket rated at 6.3 amps (slow
acting).
- control circuit 230 volt, 2 amps (fast acting).
- control circuit 24 volt d.c., 4 amps (slow acting).
Boiler temperature control
The Remeha Quinta Range has electronic
temperature control with flow and return
temperature sensors.
The flow temperature can be adjusted between
20 and 90°C.
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.
Low water protection (flow and content)
The Remeha Quinta Range are supplied with a
low water protection on the basis of temperature
measurement. 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
▲▲
t > 45°C)
the boiler will shut off and not lockout. If the
boiler is fired dry it will go to lockout (code 18).
External connections
All external connections (except rematic® 2945
C3) are made on the 24 way terminal strip,
located in the instrument box at the bottom of
the boiler.
