Why is my Lauda Thermostat cooling so slowly?
Your Lauda Thermostat might be cooling slowly due to several reasons. The cooling unit might be switched off, so ensure it is on. The controller output limit could be active; if so, switch it off. The condenser may be contaminated, requiring cleaning. Also, check if the temperature limit value is too high and reduce it if necessary.
What to do if my Lauda Thermostat is heating very slightly?
If your Lauda Thermostat is heating only very slightly, it could be due to several reasons: the controller output limit might be active, so switch it off. The temperature limit value might be too low, so increase it. The dynamic heating output restriction could be active, so disable it. The pump level might be too low, increase the pump level. The maximum current consumption of the device may be limited, increase the current consumption.
What does 'Low flow (cooling unit)' mean on my Lauda Thermostat display and how to fix it?
The 'Low flow (cooling unit)' message on your Lauda Thermostat indicates that the flow in the evaporator area is too low. To resolve this, check the hydraulic circuit for blockages like closed valves or jammed hoses and fix the cause. Also, the pump level might be too low, so select a higher pump level. If the hose cross-section is too small, increase it or install a bypass. The cooling output may be too high for the available flow rate, so reduce the cooling output.
What does 'Low flow (heater)' mean on my Lauda Thermostat display?
The 'Low flow (heater)' message on your Lauda Thermostat indicates that the flow in the heater area is too low. Check for blockages in the hydraulic circuit, such as closed valves or jammed hoses, and remedy them. Ensure the pump level isn't too low by selecting a higher pump level. Degas the device again, as insufficient aeration could be the cause. If the hose cross-section is too small, increase it or install a bypass. Reducing the heating output might also help if it's too high for the available flow rate.
What does 'Overtemperature protection' mean on Lauda Thermostat display?
The 'Overtemperature protection' message on your Lauda Thermostat display means that the outflow temperature is too high. Wait until the outflow temperature has cooled below the overtemperature switch-off point or set the switch-off point higher than the outflow temperature.
What does 'Gage pressure (Outflow pressure too high)' mean on Lauda Thermostat display?
The 'Gage pressure (Outflow pressure too high)' message on your Lauda Thermostat display indicates that the outflow pressure is too high. Try selecting a lower pump level. If pressure control is active, reduce the set pressure. If appropriate, increase the maximum pressure, but only if your application, hoses, etc. cannot be damaged.
What does 'Level very low' mean on Lauda Thermostat display?
The 'Level very low' or 'Low level' message on your Lauda Thermostat display means that the liquid level in the expansion vessel is low. Check hoses, connections, and consumers for leaks and fix them. Refill the missing heat transfer liquid if necessary. The liquid level can drop due to cooling or degassing, so refilling might be needed.
How to fix unstable temperature control on Lauda Thermostat?
To fix unstable temperature control (temperature fluctuates strongly) on your Lauda Thermostat, increase the pump level. Open the manual bypass in the constant temperature equipment. If necessary, increase the control parameters Xp and Tn. Increase the flow rate through the application. Reduce the load.
Why does my Lauda Thermostat switch to degas mode?
Your Lauda Thermostat may switch to degas mode if cooling water enters the hydraulic circuit through a defective heat exchanger. Ensure the suitable cooling water quality. Otherwise there is a risk of corrosion!
Why is the pump level not setting on my Lauda Thermostat?
The pump level cannot be set if pressure control is active. To resolve this, switch off pressure control by setting the set pressure to 0 bar.
