ECONCEPT SOLAR ST
5. Adjusting the flow limiter
ECONCEPT SOLAR ST is equipped with a variable-speed solar pump controlled by an advanced control system, which
optimises the flow rate in the solar circuit according to working conditions and heat demands.
For correct operation, the flow rate in the solar circuit must be preset during commissioning, by means of the flow limiter,
(fig. 31) to a value of 2 l/min per panel.
Activate the "Flow limiter adjustment" mode (see specifications in cap. 4.7 "DBM29 (ECOTRONIC tech) - Solar Controller").
Using an adjusting wrench (9 mm), operate on the control of the limiter (4 - fig. 31) and adjust the flow rate.
Deactivate the "Flow limiter adjustment" mode (see specifications in cap. 4.7 "DBM29 (ECOTRONIC tech) - Solar Controller").
6. Solar collector temperature sensor
To connect the solar collector sensor it is necessary to disconnect the resistance "A" from the terminals on the cable
"PT1000". Then connect the solar collector probe "311" to the same terminals.
