Thermostat and Actuat Operation The #6000 Series Thermostats & Stat Modules are integrated components, wking in conjunction with #5600 Series Actuats. The digital thermostats wk on proptional plus integral (PI) processing, producing a pulse width modulation (PM) output, that is similar to an analog output such as the one produced by the electronic mechanical thermostats. The PI processing identifies the offset between the actual temperature and the desired set point, within a defined differential that centers at the set point. It adjusts the control action to compensate f the difference, so that the offset can be eventually eliminated. In essence, it wks on a set point and a cycle length that is measured either in minutes in cycles per hour. The thermostats operate once per cycle. The on time in each cycle is determined by the difference between the set point and the actual temperature (the err). If the err is positive (i.e. the set point is above the actual temperature), the on time is increased from 50% of the cycle time, vice versa. If the actual temperature is right on the set point, the on time is exactly 50% of the cycle time. Essentially, PM thermostats operate f longer, shter, on times each cycle, depending the degree of err in the actual temperatures.

Actual times and temperature response will vary accding to system design, room construction details, etc. oom Temperature in F ( ) 6 7
Thermostat and Actuat Operation The #5600 Series Actuats are non-motized and activated by an electric current. This current heats a heating element in a wax filled piston chamber that in turn drives, moves, the mot insert pin, as the wax warms up and expands. Thus opening and closing the manifold module zone valve. The actuat has a full close to full open time range of.5 to 6 minutes (depending on the residual temperature of the heating element, and the wax piston chamber from the previous cycle). king in conjunction with slow acting actuats, PM thermostats are essential f slow responding, high thermal mass systems. Slow responding means there is a long delay from when a temperature change is sensed by a thermostat, and after it is turned O. ikewise, a high thermal mass system means that heat continues being released f a long period of time after a thermostat was turned down. If an O/OFF thermostat is used instead, cycles of overheating and underheating will be unavoidable. An O/OFF thermostat turns O only when the actual temperature is below the desired set point. In a slow responding system, the actual temperature can continue to dip even after the thermostat has turned O. This is because the heat initially applied to the system is being used to stock up the thermal mass instead of warming up the space.

/ool Thermostat Interlock iring Application: A single cooling zone can often encompass multiple radiant heating zones. A heat/cool thermostat will turn off heating to its zone when cooling is on. However, all the other heating thermostats in the cooling zone may still call f heat. This means that the heating system and cooling system could be active at the same time and wk against each other. Option - Interlock: hen the heat/cool thermostat calls f cooling, the relay will interrupt the heating system s connection to the boiler. This will prevent the boiler from firing. Advantages: ing and cooling systems won t be active at the same time. Disadvantages: Zones that may need heat won t receive any. Option - Most omft: /ool Thermostat ing and cooling systems wk independently (and possibly simultaneously, except f the zone controlled by the /ool Timer Thermostat). This option would be used in flo warming applications. Advantages: Straight fward wiring; no interlock Disadvantages: Except f the zone controlled by the heat/cool thermostat, the heating and cooling systems may wk against each other depending on thermostat settings and zone environment, resulting in extra energy usage.

Option 3 - Interlock with Outdo eset ontrol: If the outdo temperature is warm enough, the heating system will be in arm eather Shut Down (SD) mode. hen the heat/cool thermostat calls f cooling, the relay will interrupt the heating system s connection to the boiler. If the heating system isn t in arm eather Shut Down (SD), this will prevent the boiler from firing. The heating system pumps will still run, so any heating zones that may be calling f heat will still receive any residual heat in the system. /ool Thermostat T Advantages: Outdo temperature feedback Disadvantages: Outdo eset ontrol required T T Flo Sens ' G Y 3355 DIP Switches Perm.
