Steam traps separate condensed steam (condensate) from steam; steam is corrosive and they ultimately leak. Maintenance is an issue because the losses are generally hidden and it costs at least $20 to test a trap. Higher pressures lead to higher losses; a single leaking trap can lose $100 or $10,000 of steam each year, some systems have 10,000 traps.

This is a tool that sits between opentherm thermostats, and a PC. The firmware talks to each thermostat, and reports via the serial port.

Simple 5 region thermostat with PIC16F690 using NTC's as a sensors driving 5+1 relays. Thermostat do not use PID control but a simple on/off with hysteresis (like ordinary mechanical thermostat would - note that function in source that decides to turn heater on/off is called pid() but that's not how decision is made). Note that it's designed to measure 5 regions and control 5 groups of heaters but *all* of them are trying to reach *same* temperature. If a region goes too much off the set...
