What to do if my Senztek solastat-1 Thermostat has no operation, display, or lights?
If your Senztek Thermostat isn't working, showing no display, and has no lights, it could be due to a power issue. First, check the mains outlet to ensure it's working. Then, inspect the fuses to see if any have blown.
Why is the POWER light ON but there is no display or a corrupted display on my Senztek solastat-1 Thermostat?
If the POWER light on your Senztek Thermostat is on but the display is either blank or corrupted, it could be due to a power brownout (mains power not running at full voltage) or a faulty unit. Try switching off the power while the mains power is in a brownout condition. Alternatively, switch off the power for 10 minutes, then switch it back on to see if the unit operates normally. If the issue persists, the unit may need repair.
What to do if the Senztek solastat-1 display is on, pump is not running, but it's sunny outside and the pump light is ON?
If your Senztek Thermostat display is on, the pump isn't running despite sunny conditions and the pump light is on, it could be due to a damaged or disconnected pump, or the pump timer has turned the pump off. Check if the pump has become unplugged. Wait one minute for the pump to restart.
Why does the hot water drop significantly at night with my Senztek solastat-1, even with little or no draw off by the user?
Significant hot water drops at night with little usage on your Senztek Thermostat system can be attributed to a few potential issues: the system might be reverse thermo-siphoning, it could be located in a high frost area, or the tank may be losing heat. The non-return valve might not be fitted correctly or is malfunctioning. Discuss non-frost sensitive options with your energy provider. Consider installing better insulation on your hot water tank.
What does ‘Lo’ on the display of my Senztek solastat-1 Thermostat mean?
If you see ‘Lo’ on your Senztek Thermostat display, it indicates that the sensor is reading a temperature below -20°C [-4°F]. Check the outside temperature.
What does ‘Hi’ on the display of my Senztek solastat-1 mean?
If you see ‘Hi’ on your Senztek Thermostat display, it indicates that the sensor is reading a temperature above 159°C [318°F]. Ensure the collector has water in it.
What does ‘SSd’ on the display of my Senztek solastat-1 mean?
If ‘SSd’ is displayed on your Senztek Thermostat, it means the system is in ‘Smart Shut Down’ mode. Contact your installer or maintenance technician if the display shows ‘SSd’ for more than 12 hours.
