2 Introduction Note: The information supplied in this manual is for guidance only - no part of this may be used for any agreement, whether express or implied, or to form any contract. Thermo Technologies reserves the right to change specifications without prior notice.
3 INSTALLATION Note: This installation procedure is for guidance only, and the installer should verify its suitability. Make sure that the solar system is physically installed, manually tested, and ready for controlled operation. he following sa fety precautions are strongly recommended: 1.
4 strap the sensor to the collector outl et pipe or the absorber (flat plate collectors) that projects from the collector housing. Ideally, house the collector sensor (encased in a suitable sensor pocket) into a T - piece on the collector return outlet.
5 Undo the screw at the top of the housing. The control electronics are mounted on the enclosure cover. The controller enclosure can be screwed to the wall with cable entry grommets pointed downwards. Use the supplied plastic bridges to secure pow er and sensor cables.
6 ower Connections: A small blade screwdriver may be used to fasten miniaturized terminal block screws while the corresponding wire is inse rted. NOTE 1: Always disconnect the controller from power supply before opening the housing. NOTE 2: The controller should be properly grounded.
7 Use selection keys ïð during normal system operation to display the desired parameter: T1 xxx Collector temperature in o F T2 xxx Tank temperature in o F T3 xxx Reading of the third sensor; if the.
8 RUV X.X – This display shows the software revision number. NR O – This is PROGRAM 0 which indicates simple operation of unit as a U niversal S olar D ifferential T emperature ( USDT ) controller. Change this value to 1 ( NR 1 ) for activation of the third sensor or puls e flow meter input (PROGRAM 1) .
9 symbol while the pump is running. User can switch to manual mode by pressing ò k ey. By pressing ð key while centerline blinks, a hand symbol G in lower line shows manual operation. Pressing ð one more time lets you turn the pump ON or OFF . By pressing ñ key you change the pump operation.
10 max = 2 Pump runs again below this set point (T3) Energy calculation mode (PROGRAM 1) : USDT 2004 computes the energy production as a function of the temperature diff erential and fluid volume. In addition, the system anti - freeze (Glycol) percentage should be entered as it affects the thermal conductivity and heat transfer rate.
11 START Starts pump at pre - set insolation (solar radiation intensity) ALARM Enables/Disables protection functions BTU Energy calculation and setting ensor Designation – USD T 2004 accepts two different sensor types or a reference value . User can program a constant reference temperature instead of a sensor output.
12 circulation pump runs when the collector temperature is below a programmable minimum temperature, shown by = symbol. The pump stops as soon as the temperature in the solar loop reaches a safe region programmed by the ? symbol. This feature is also disabled at the factory by entering - 4 o F.
13 2 OPEN Disconnection in sensor 2 wiring OK System operates normal NO CIRC r T is more than 108 o F in last 30 minutes OK CIRC Pump is running CLEAR Clears NO CIRC display after correction nergy calculation - Energy gain is calculated by obtaining the temperature increase of heat transfer fluid across the solar collector.
14 T roubleshooting In general, all of the settings in the menus Par and Men and the terminal should f irst be checked if there is a malfunction. Malfunction, but "realistic" temperature values: • Check program number. • Check the switch - on and switch - off thresholds and the set differential temperatures.
