The SolaStat-Plus-2 (with the addition of the SolaStat-Rly) allows intelligent control of the electric element used in the hot water tank (HWC control). The SolaStat-Plus-2 can prevent the electric element coming on for a programmed time interval when Solar Hot Water is already being transferred into the hot water tank (Holdoff Timer). -

Test: Briefly pressing this button will cause all the lights to flash on for 3 seconds then display for 3 · seconds the number of times the SolaStat-Plus has operated the pump. This count will reset and start again after ‘999’. -

Page 7: Solastat-Plus Safety Instructions
Do not allow the sensor cables to come within 10mm of the high voltage connectors or components inside the enclosure. The HWC output must be used in conjunction with a SolaStat-Rly. This is due to the high power levels used by hot water electric elements, and completely isolates the SolaStat-Plus from the HWC circuit. -
Page 8: Solastat Plus Mounting
The ‘TANK’ sensor is best fitted into a metal immersion ‘pocket’ in the upper region of the HWC. For the SolaStat-Plus-2 the position of the Tank sensor will vary the amount of water in the HWC that will be controlled at the required temperature. As an example for a 300l vertical tank mounting the sensor 1/3 of the way down from the top of the HWC will give about 100l of water that is heated within the control parameters. -

Connect the Pump. Plug in the pump to the ‘PUMP’ socket on the SolaStat-Plus. This should be the correct type of pump for domestic solar hot water circulation and not exceed the horse power (hp) rating as specified on the label on the side of the enclosure. -
Page 10: Power Up
Note on BioSafe After Power-up. When the SolaStat-Plus is turned on either for the first time or after a power failure the BioSafe 24 hour timer starts from power up (unless the temperature in the tank is greater than the BioSafe Temperature) and the Holdoff Timer will start from the next pump activation. - Page 11 The ‘FROST’ can be adjusted using the ‘+’ and ‘-‘. All the values are now entered. The values can be checked by simply pressing ‘NEXT’ to cycle through all the values noting which light is on and what value is displayed (as per SolaStat-Plus Programming Table).

12. Reconnect the SolaStat-Plus and turn on the power. 13. Check sensor is reading correctly and check SolaStat-Plus operation as per “What You Should See” section of this manual. The table below has the correct resistance values of the sensor at different temperatures. The sensor must be removed from the SolaStat-Plus to measure these values correctly. -

The SolaStat-Plus controllers have an optional factory setting called ‘Pump Timer’ to assist in pump cavita- tion recovery. After the pump has run continuously for approximately ten minutes, it will turn off for one minute.

@Mr. Anderson Clearly what I need is the access code and how to input that code.
how can i acsess frost protection values
To access the frost protection values on the SolaStat-Plus:
1. Enter programming mode.
2. Press ‘NEXT’ until the ‘FROST’ light turns on continuously—this indicates the frost value is being displayed.
3. Use the ‘+’ and ‘–’ buttons to adjust the value.
4. Press ‘STORE’ to save the value to permanent memory.
If no key is pressed for a minute, values are automatically saved and the unit exits programming mode.

solastat -2-3 can i change code to re program controle values. My colector has frozen twice.
Yes, you can reprogram control values on the SolaStat-Plus to help prevent your collector from freezing. The ‘FROST’ value can be adjusted using the ‘+’ and ‘–’ buttons when the ‘FROST’ light is on. Once set, press ‘STORE’ to save the values and exit programming mode.
