8.2. Collector
In this menu are settings for the work of the collector (one or two fields (if
they exist)) and it’s protection functions.
8.2.1. Collector 1
In this menu settings for work of the collector 1 are set (maximum
allowed collector temperature, enabling temperature of the collector 1
for start of the collector pump, puls start of the collector 1 pump and
collector sensor address).

8.2.1.1. T MAX

collector
Setting of the maximum temperature of the collector 1.
Pump of the solar collector field 1 works to the temperature in collectors
[T MAX collector 1] after which stops (to protect the fittings from to high
temperature, steam in the collectors and inability to operate the pump
until temperature in the collectors is lower then set max. temp. of the
collectors.
When temperature in the collectors falls below [T MAX collector 1 - 4°C]
pump of collector field 1 starts to work again if other conditions are met.
NOTE:
[T MAX collector] must be set according to the boiling point of the
solar fluid in the solar system and always must be lower than the boiling
point.
8.2.1.2. T enable coll.1
Setting of the minimum temperature of the collector 1 at which
circulation trough collector 1 starts (working of the collector pump).

8.2.1.3.Pulse collector start
In this menu are additional menus for setting the parameters for the
pulse start of the pump (kick) of the collector field 1
If collector sensor isn’t installed into collector (but somewhere on the
flow tube) or there are more collectors in the same field, it’s
recommended to enable pulse start which in case of the inactivity of the
collector pump, periodically starts it for some time to have better
temperature reading of the solar fluid on the collector sensor.
NOTE:
to often and to long work of the collector pump can
unnecessarily cool down the tank! Work and pause time of the pump
depends on the size and location of the collector field and collector
sensor.
