Heating controller Olympia HT 430-22 Energy Saving — Olympia HT 430-22 heating controller

The Olympia HT 430-22 Energy Saving heating controller is a programmable thermostat designed for regulation of central heating systems in homes and small commercial premises. It enables scheduled temperature control, automatic switching between comfort and setback modes, and offers functions aimed at reducing energy consumption while maintaining indoor comfort. The device integrates with conventional heating installations to control boiler operation according to pre-set time and temperature profiles.

Advantages

The controller provides precise temperature scheduling with multiple daily periods, helping to optimize heating cycles and lower fuel or electricity use. It supports manual override for temporary adjustments without altering stored programs, and its compact design allows straightforward installation in typical heating control panels. Its energy-saving focus combines time-based control with setback temperatures to reduce runtime while keeping rooms comfortable when needed.

Suitable for

• Residential central heating systems (single-zone control)
• Small commercial spaces with simple heating schedules
• Buildings where programmed temperature setbacks are used to save energy
• Retrofitting traditional boilers with a programmable control

Key specifications

• Programmable weekly schedule with multiple switching times per day
• Comfort and setback temperature settings
• Manual override option without deleting stored programs
• Compact form factor suitable for mounting in control panels
• Designed for controlling conventional boiler activation circuits

How to use

Install the heating controller according to the manufacturer's wiring diagram, connecting the unit to the boiler control circuit and supply power as required. Program weekly schedules by setting the desired comfort and setback temperatures and assigning switching times for each day or groups of days. Use the manual override to temporarily change the temperature or switch the system off for brief periods; the stored weekly program will remain active. Periodically review and adjust schedules and temperature setpoints to match seasonal requirements and occupancy patterns.

Usage recommendations

For energy-efficient operation, set lower setback temperatures during unoccupied hours and raise comfort temperatures shortly before occupancy. Regularly maintain the heating system and verify correct installation to ensure the controller accurately reflects room temperatures. Consult a qualified heating technician for installation if you are not experienced with central heating wiring.
