Setting up hydronic heating system in EnergyPlus

edit

Hi folks,

As a school project about domotics and energy I want to run some simulations using energyplus. Howerver in my country (holland) in homes they use 99% of the time hydronic heating systems which includes a gas-heated boiler and some radiators. (see picture) Unfortunataley I am having some issues with setting this system up, iIdont know which thermostat(s) to choose from. If anyone could help me I would highly appreciate it!
