SolaStat-Plus Power Up.
Before you connect the power;
1. Read safety instructions, warnings and limit of liability before proceeding.
2. Complete all the installation and securely mount the SolaStat-Plus.
3. Power outlet socket to be installed by a qualified electrician.
4. SolaStat-Rly to be installed by qualified person.
5. Ensure suitable over-current protection and RCD Protection for the SolaStat-Plus and pump is in
place.
6. There is no water, metal shavings or other electrical hazards to contaminate the plug, socket and
surrounding environment.
7. For the SolaStat-Plus-2 Only. The Hot Water Thermostat for the Electric Element MUST be installed
and MUST be set higher than the temperature of the HWC BioSafe and Reheat adjustable values for
the HWC Control Modes to operate correctly. The Hot Water Thermostat for the Electric Element is
only used as a fail safe feature and in normal operation will never operate. We recommend setting
the Hot Water Thermostat to the Maximum Temperature. Refer to the Trouble Shooting Guide for
errors that can be caused by incorrect Hot Water Thermostat settings.
Only then;
Plug it in and turn it on.
What You Should See.
The first thing you should see after power up is;
1. A digital readout of the ‘TANK’ temperature in degrees Celsius.
2. On the left the ‘PWR’ light and the ‘TANK’ light should be on.
3. On the right the lights will be on depending on how the solar hot water system is operating.
The pump operation can be tested by pressing the ‘PUMP’ button. This will turn the pump on as long as the
button is held down, unless of course the pump is already on in normal operation.
The SolaStat-Plus is now installed and should be working. It would be best to observe some solar hot water
pump cycles but this will rely on the sun shining. Check all functions are working correctly before leaving
the installation.
Note 1. See User Guide for explanation of display and status lights.
Note 2. See “Trouble shooting” section if system not working correctly.
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. All timers are approximate only.
SolaStat-Plus Programming.
If the Adjustable Values from the factory are inappropriate for the installation (see included document
stating programmed values) then the unit needs to be programmed.
The programming access code is for distributor or installer use only, as using incorrect Adjustable Values
can cause inefficiencies in the system or cause damage to the system voiding the warranty.
Once new values are ‘stored’ they are permanently written into memory and will be retained when power is
removed.
