Very old Heating-Cooling system...anyone recognize it?

I live in a condo complex that was built in the 70's and works by using what seems to be a very unique method. Water is circulated through a series of pipes into all the condos, these pipes feed into a galvanized metal box which houses a large blower motor (GE 5ksp39mg 6162AT). The pipes run through a radiator. Hot or cold water runs through this setup depending on the season. When the thermostat senses a certain temperature, it turns the blower motor on, which draws living space air through the radiator, and into the hvac ducts which feed into the rooms. This motor runs until the desired temperature is reached.

The thermostats are line-level. I cannot for the life of me find a line-level PROGRAMMABLE thermostat out there.

Does anyone know if this is even possible?

All help much appreciated.

This method is typical in large hi-rise buildings.

I don't think I was very clear in my original post. Each condo unit has it's own blower motor and it's own series of ducts that feed into all the condos rooms.

The only shared thing is the water coursing through the pipes which goes through the radiator, which then returns back to the heater/cooler located in a central building.

Thanks LawnGuy.

The main question is, is there a programmable thermostat available?

They make programmable line-volt thermostats. Saw them at Home Depot.
