I have a Vaillant VRT350F programmable thermostat connected to an Ecotec Plus 28 boiler.
The thermostat was acting up so I did a factory reset. Everything is now working fine however I wasn't sure what I should set the Control Strategy to - I only have the user guide and not the installation guide and this doesn't seem to be mentioned in any detail.
The options were Two-Point and Analogue.
Can anyone advise what this relates to and what the two options mean?
Thanks in advance
