ST-460 - Watt

Tech2. Protection against overheating the collector .If overheating(alarm) temperature is reached, the regulatorswitchesto the so-called overheating status of the collector, on the display, thefollowing symbol appears: . The pump starts to work in order to cooldown the tank of the collector until achieving the container's maximumtemperature or until drop in the collector's temperature by the alarmhysteresis value (see: SERVICE MENU > Solar collector > Alarmhysteresis). In the case of two tanks, both are used for cooling theoverheated collector down (at the same time or successively,depending on operation algorithm setting)3. Heat container protection.In the case of collector overheating, each tank can be heated up to nomore than the set value of the maximum safe alarm temperature. Afterreaching the maximum temperature, the pump of a given tank will beshut off (in the system of two tanks with a valve, switching the circulationto the other tank will occur).3. Fuse.The regulator has a fuse tubular insert type, WT 3.15A, protecting thegrid.NOTE: do not use a fuse of a higher value. Assembling the fuse with agreater amperage can cause damage to the controllerVI. MaintenanceIn the TS-460 controller, before heating season and throughout itsduration, technical condition of wires should be monitored. Check alsofastening of the controller and clean it from dust and other dirt.- 29 -
