External Sensor:
This option is useful for collectors that require the sensor to be mounted on the piping external to
the collector manifold.
Select
External sensor
and press
(>)
to highlight the line.
- Now select
yes
[using the
(+)
or
(-)
keys] if the collector sensor is not mounted directly on the
collector (e.g. on the return pipe). This function will energize the collector pump for 30 seconds
twice per hour to ensure that the collector fluid temperature is accurately measured and avoid
collector short cycling.
1.6 Protection function :
- Once the line is selected, press
(>)
to enter the submenu.
The
Maxtemp
setting is used in the following three protection functions which are designed to
prevent overtemp in the collectors. If one or more of the protection functions are activated, the
system will automatically activate when the collector temperature reaches the
Maxtemp
threshold regardless of the tank temperature settings.
(
Maxtemp
is adjustable from 230°F to 302°F with factory default set at 248°F)
For safety, however, the pumps will automatically shut down when the water temperature in the
tank reaches 203°F.
