Frequently Asked Questions - MD22S Salus

How do I install the Salus MD22S thermostat?

Turn off power to your heating system. Remove the old thermostat, note the wiring. Mount the MD22S base plate using the provided screws and plugs. Connect wires to terminals according to the wiring diagram. Attach the thermostat faceplate and restore power. Refer to the installation manual for details.

What type of batteries does the MD22S use?

The MD22S uses two AAA alkaline batteries. Do not use rechargeable batteries as voltage may be insufficient. Replace batteries once a year or when the low battery icon appears.

How do I set the time and day on the MD22S?

Press and hold the SET button for 3 seconds. Use the ▲ or ▼ buttons to set the hour, minute, and day. Press SET to confirm each step. The unit will automatically adjust for daylight saving if enabled.

Can I program the MD22S for different temperatures on weekdays and weekends?

Yes, the MD22S offers 7-day independent programming. You can set up to 4 time periods per day (Wake, Leave, Return, Sleep) with different target temperatures for each.

What does the 'Frost Protect' function do?

Frost Protect keeps the temperature above 5°C (41°F) to prevent pipes from freezing. It activates automatically when the thermostat is in off mode or if the temperature drops too low.

Why is my MD22S display blank?

Check if batteries are inserted correctly and with the correct polarity. Replace with fresh AAA alkaline batteries. If the issue persists, the thermostat may be faulty and require replacement.

How do I reset the MD22S to factory settings?

Press and hold the RESET button (located on the side or back using a paperclip) for 5 seconds. All settings will be erased, and the thermostat returns to default programming.

Is the MD22S compatible with my heating system?

The MD22S works with most gas, oil, and electric heating systems that use a 24V control circuit. It is not suitable for high-voltage systems (e.g., 230V). Consult a professional if unsure.

How do I clean the MD22S thermostat?

Wipe the exterior with a soft, dry cloth. Do not use water, solvents, or abrasive cleaners. Avoid getting moisture inside the unit.

What should I do if the MD22S is not heating?

First, check that the thermostat is set to HEAT mode and the temperature set point is higher than the room temperature. Verify the batteries are good. Ensure the heating system power is on. If it still doesn't work, contact a qualified technician.

USER MANUAL MD22S Salus

The following instructions are designed to help the engineer to install and maintain the Magnetic Filter safely and efficiently and should be followed and adhered to at all times. Make sure there is a water-filling pipeline behind the filter. During maintenance, check whether the lid seals are worn or damaged. The best practice is to replace the lid seal at each repair.

1. INTRODUCTION

The Magnetic Filter is specially designed for central heating systems. It can remove almost all the harmful black suspended iron oxide particles accumulated in the central heating system and protect the complete central heating system.

2. MOUNTING RECOMMENDATIONS

The filter can be installed in a variety of ways, for example: be installed at any locationonthemainpipeline. However, it is recommended to be installed after the last radiator and before the boiler on the primary return pipework for maximum protection and efficiency.

Note: It is important to have adequate access for maintenance and servicing when determining a suitable installation location.

1. Cut and remove the section of the pipe according to the product installation length;
2. Install the valves onto the pipework, hand tighten only at first, then tighten securely the valve to the pipe;
3. Install the filter housing and tighten it;
4. Adjust the Angle and secure the filter;
5. Make sure the valves are open, allow the system to fill, open, and vent the filter through the air vent valve, close when complete.

5. MAINTENANCE AND SERVICING

Note: Prior to carrying out any maintenance work, isolate the electrical supply to the boiler allowing the water to cool down to a safe working temperature.

1. Close both the isolation valves;
2. Open the drain valve, place a bucket or similar receptacle below ready to collect the debris. Take out the magnetic bar and store in a safe place;
3. Open the inlet valve to flush out the debris, once all the debris has been removed introduce a suitable chemical inhibitor into the system, we recommend Salus LX1 inhibitor, refit the magnetic bar;
4. Open the inlet and outlet valve, vent the filter through the air vent valve close when complete. Check for any leaks;
5. Complete any relevant documentation.
   IE: Dates and inhibitor used.

Note: It is recommended that the magnetic filter is installed and maintained by a competent and qualified person. Any queries arising from either installation or servicing, contact SALUS Controls at [e-mail]
