Ideal Logic System S30 Boiler Details
The Ideal Logic System S30 is the top-output model in the Logic System2 range. It is a condensing system boiler with full sequence automatic spark ignition and fan-assisted combustion. The boiler comes fully assembled with a circulating pump, pressure gauge, PRV and CH expansion vessel, so it suits homes that heat water in a separate cylinder. The casing is white-painted mild steel with a white polymer front panel. The boiler must only be connected to fully pumped, sealed heating systems.
The user control is simple: a Temperature Knob, a Mode Button, a Restart Button, a pressure gauge and a high-resolution status display. The display shows a flame symbol while the burner is lit. "F" codes identify faults and "L" codes identify lockouts. In most lockout cases you can press Restart. If the boiler fails to light after five attempts, it shows L 02. If it is reset five times within 15 minutes, it locks out with L 0C.
Intelligent Load Optimisation reduces on/off cycling. If the flow temperature reaches the CH target plus 4°C, the burner switches off. When it relights, it modulates down to minimum rate over 60 seconds and stays there for 10 minutes. This helps when the heat load is below the boiler's minimum output. Built-in frost protection fires the boiler if the water drops below 5°C and runs until it reaches 19°C. A daily pump exercise also runs a brief self-check every 24 hours.
The S30 can use an outside sensor for weather compensation. With a sensor fitted, the knob sets a nominal room temperature between 10°C and 30°C instead of a flow temperature, and hot water to the cylinder is fixed at 80°C. Without a sensor, the boiler can be switched to 2x Switched Live mode, which uses separate CH and DHW demand inputs. OpenTherm controls, Halo controls and Ideal's Link remote monitoring are supported. Lowering the room thermostat by 1°C can cut gas use by up to 10%.
A siphonic 75 mm condensate trap reduces the risk of freezing. If the external pipe freezes, the boiler gurgles and then locks out. You can thaw the pipe with warm, not boiling, water or a heat pack. The installer mode is opened by holding Mode and Restart for more than five seconds. It shows the last three faults and offers maximum and minimum rate tests, a five-minute venting function, and pump speed settings of 70% or 100%.
Servicing is straightforward. The single ignition/detection electrode has a 3.5 mm spark gap, and the burner can be removed without draining the boiler. Ideal approves specific inhibitors, including Fernox, Sentinel X100, Adey MC1, Scalemaster SM-1 PRO and Calmag CM100. The system must not be filled with artificially softened water. The boiler contains no asbestos, mercury or CFCs. It must be serviced every year by a Gas Safe Registered engineer, and the Benchmark checklist must be completed to keep the warranty valid.
