55. y will alternate between the Day Ext and the Extended Time balance remaining in minutes indicating the Extended Day mode Auto Manual Open Bypass MANUAL The switch must be in the AUTO position for the SRC Platinum to control the Vacuum Pump Burner and the Motorized Valve In the Open Bypass position the Vacuum AUTO Pump Burner and Motorized Valve Open relays will run constantly That will leave the burner to run on its limits and the motorized valve will be fully open In the OPEN Manual position the Vacuum Pump and Burner will run constantly The Adjust dial BYPASS knob will control the valve opening percentage When the SRC Platinum is in the Open Bypass position no normal functions will be executed The display will change to read the total amount of time the control has been in Bypass Open The display will show the number of days hours and minutes the SRC Platinum has been in Open Bypass The Bypass Open switch directly connects the Normally Open contacts 4 to 5 contacts 9 to 10 and contacts 15 to 16 Therefore if there is no heat test the Vacuum Pump and Boiler or Motorized Valve by putting the control in Open If the units do not run the problem is not with the SRC Platinum panel The Manual position activates the Vacuum Pump and Burner relays But allows the adjustment of the Valve opening manually using the Adjust turn knob Remember that the Pulse Close Pause Length will still take effects in this mode
56. ycle principle which was created specifically for steam heating systems The Cycle concept was developed by Heat Timer to overcome the inabilities of standard thermostatic controls to cope with the unique challenges of steam heating The temperature of steam can not be regulated as with hydronic systems In addition steam heat can not be switched on and off instantaneously as with hot air systems Instead it takes time to build up a head of steam Once the system starts heating up it has momentum which can not be quickly stopped 100 Open 10 at the Day Cutoff Opel 50 Freezing ur Heat Timer s theory of steam reset heating is as follows Pulse the valve open to a limited valve position very slowly filling the system with 80 steam and starting a timed heating period The valve position will be determined by two adjustable points The first point is the percent the valve should be open when the control starts giving heat 1 e at the Day Outdoor Set Point typically 55 F The second point will be the percent the valve should be open at freezing i e at 32 F The time of the heating period will vary according to the Outdoor temperature OD and the Heat Adjustment settings When this timed heating period is over the valve will close either partly or fully as adjusted by the operator This will cause two things to happen First as steam turns back into 30 water all the energy it carries is released in the form of BTUs which
57. zed valve opening by 1096 above the Day calculated percentage There are two types of boosts in the SRC Platinum The manual boost which allows the change of the amount of time required to start the Boost before the Day schedule The Vari Boost increases the motorized valve opening as the manual boost The difference is the initial start time The Vari Boost depends primarily on the Outdoor temperature and the Boost Adjustment boost curve selection See Boost and Early Shutdown a A a o Early Shutdown is a feature that allows a commercial building that is not occupied during Night heat level to be shutdown earlier The SRC Platinum calculates the time period from the last Schedule setting for that day based on Outdoor temperature OD and the Boost Adjustment boost curve selection 55 50 45 40 35 30 25 20 15 10 5 0 5 10 15 20 25 The warmer it is outside the earlier the SRC Platinum will shift to Night At 55 F Outdoor Temperature in F Outdoor Temperature OD the Early Shutdown is the longest of 90 minutes At 25 F Outdoor Temperature OD there is no Early Shutdown or Early Shutdown is 0 minutes See Boost and Early Shutdown arm up Prior to Morning Boost 0 to 180 Minutes Duration of Morning Boost in Minutes EARLY SHUT DOWN Sequence of Operation E a When the SRC is powered up the contr
