Landlord Thermostat Recommendations?

[William Conrad]

I'm looking for a good landlord thermostat. In the multi-family I own, two furnaces heat four apartments, so there is no way for me to divide the heating bill amongst the tenants. So, my best bet is to make the apartments as efficient as possible and control the heating from remotely. I'm looking for something that gives me remote access and isn't hackable by the tenants. If they aren't paying for the heat, they have no incentive be smart about the heating bill. So, it falls on me to monitor it. Any good thermostat products out there I should know about?  Thanks for the help!

We use landlord stat by Chicago temperature control. It has setback to 68 after 2 hours and tops at 70, it is low tech but we weren't planning on an internet version. It is also not obvious that it is capped. I know you can go higher tech but it seems to do ok. I do want a shutoff on the boiler for summer but because it also heats the water it is a bit more complicated.
