PLEASE NOTE
House slow to heat up
It can take several hours to reach the temperature set
on the room sensor dial.
Balancing radiator system
In older houses especially, the radiator system may
not be balanced. To further optimise the heating
system, it is worth balancing the system to get the
right water flow through each radiator relative to the
heat output of all radiators. Small radiators should
have less flow than the larger ones. This makes for
better heat distribution through the house. The larger
the house and pipe network, the more benefit
balancing will provide.
In certain cases the heating system can be short
circuited and more or less cease to operate.
If the radiator in the room where the room sensor is,
is too big compared with the other radiators in the
house, some of the other rooms can be too cold. This
can be rectified by modifying the output of this
radiator with a manual dial or with the pressure
reduction device in the return valve.
Balancing is particularly important in sites with a
storage tank or heating pump. Balancing makes the
return temperature as low as possible, which increases
the storage capacity of the tank and the effectiveness
of the pump .
Fault tracing
For ease of installation and fault tracing, ERA
immediately goes into start up mode for 30 minutes
every time the power is connected.
If the max setting dial is at an end point at start up,
the red+yellow light will blink for 5 seconds. The
direction of movement can be set during this time.
If there is a fault (short circuit or power loss) in either
or both sensor and cable to it, ERA will always go to
closed position and then open again for 20 seconds,
which corresponds to the mixing valve opening to
position 1 on the ESBE mixing valves.
This is designed to deliver sufficient heat to protect
the heating system against frost.
If there is a fault with the room sensor, the green light
will blink every 4 seconds.
If there is a fault in the flow pipe sensor the green
light will blink every other second.
If there is a fault in both the flow and room sensor the
green light will blink rapidly for 3 seconds followed
by a longer blink.
PLEASE NOTE when the RED or YELLOW
light is blinking, this indicates that the mixing
valve is fully open or closed not that there is a
fault.
