ST – 460 operation manualtemperature on the collector increases above the temperature of thetank by the value of the solar pump activation delta.When the pump deactivates after reaching the set temperature,its reactivation will take place if the temperature falls below the setvalue by the value of the tank hysteresis (the hysteresis value is setin: SERVICE MENU > Accumulation tank > Tank hysteresis)2. Collector defrosting.Using this function, you can manually activate the collector pumpin order to melt snow on the solar panels. After activation, this mode isactive for the time specified by the user, and then the controller returnsback to the automatic operation (the defrosting time is set in: SERVICEMENU > Solar collector > Defrost time). The function can be switched offmanually after a shorter operation time by selecting a different operationmode.3. Holiday mode.After holiday mode activation, the pump works when thetemperature of the collector increases up to the overheating temperaturevalues (SERVICE MENU > Solar collector > Overheating temperature)reduced by the value of the Holiday delta parameter (SERVICE MENU >Accumulation tank > Holiday delta), or when the collector temperature islower than the temperature of the tank. When this condition is met, thepump activates to cool down the collector (or the container) Deactivationof the pump takes place after reducing the temperature by 5°C. Such apump operation algorithm in the holiday mode allows for maximumenergy saving.4. Manual operation.In this function, in order to control the installation devices, theuser can manually (by pressing the selected device icon) activate anddeactivate:-solar pump,-second solar pump or switching valve,-additional device (voltage-free contact e.g.. for firing up the pelletboiler)III.c) TimerIn this function, the user sets current time, according to which theregulator will be operating.- 8 -

III.d) Internet ModuleTechNOTE This type of controlling is possible after purchasing additionalcontrol module ST-500, which is not provided with the standardversion of the controller, and connecting it to the controller.The Internet Module is a device permitting remote control of thecollector operation over the Internet or local network. On the homecomputer screen, the user controls the status of all the solarinstallation equipment and the operation of each device is presentedin the form of an animation.After activating the Internet module and selecting the DHCPoption, the controller will automatically download parameters from thelocal network such as: IP address, IP Mask, Gateway Address andDNS Address. In the case of any problems with downloading thenetwork parameters, it is possible to set these parameters manually.The method of obtaining the local network parameters has beendescribed in the Internet module manual.The Resetuj hasło modułu function may be used when the userhas changed on the login page the factory user's password for his ownpassword. When a new password is lost, it is possible to return to thefactory password after resetting the module password.III.e) GSMNOTE This type of controlling is possible after purchasing additionalcontrol module ST-65, which is not provided with the standardversion of the controller, and connecting it to the controller.The GSM module is an optional device cooperating with thecollector controller, allowing remote control of the collector operationwith the use of a mobile phone. The user is notified with a textmessage on each test alert of the solar installation controller and bysending an appropriate SMS message at any time, he receives areturn message with the information on the current temperature of allsensors.The ST - 65 module can operate also independently from thecollector controller. It has two inputs with temperature sensors, singlecontact input for use in any configuration (detecting shortcircuit/opening of contacts) and one controlled output (e.g. possibilityto connect additional contactor to control any electrical circuit).When any sensor temperature reaches the set maximum or- 9 -

ST – 460 operation manualminimum temperature, the module will automatically send a textmessage with such information. It is similar in the case of a short-circuitor opening of contact input, which may be used e.g. for simple protectionof property.III.f) Chart PreviewThis function allows the user to see charts describing thefollowing parameters:•total energy obtained as a result of the solar collector operation,•total pump operation time,•average pump operation time•average differential temperature between the collector and thetank,•average pump rotations.The charts and the average values show particular parameters overa specified time period: Daily, Weekly and Monthly. Pressing a specificchart bar (e.g. hour in the case of a weekly chart) shows particularvalues at the bottom of the screen. For each time interval, specificationof particular values is added.III.g) HighlightingThe parameter regulates the level of brightness of the display afterit turns blank.III.h) LanguageThe user can select the language version of the controller.III.i) InformationSelecting this option displays the logo of the controller'smanufacturer and the current program version.III.j) Factory settingsThe regulator is pre-configured for operation. However, it should beadjusted for own needs. Return to the factory settings is possible atany moment. Activating the factory settings option cancels all theuser's controller settings and replaces them with the settings saved bythe controller manufacturer. From that moment, own controller- 10 -

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 -
