SRC (Vacuum)

Subatmospheric Vacuum Steam Outdoor Reset Heating Control
Available with optional Internet , BACnet, or Modbus communication

 

 

Overview

 

The SRC Platinum is a vacuum steam outdoor reset control for sub-atmosphere steam systems. The SRC Platinum will start/stop the vacuum pump and boiler, and modulate the steam motorized valve to vary (cycle) the duration of seam flow into a building’s radiation in accordance with changes in outside temperature. The colder it is outside, the more steam that is allowed to enter the buildings radiation.

 

The SRC Platinum offers multiple communication options. The Internet communication package offers a large group of optional sensors that can be monitored, logged, and alarm set. In addition, Heat-Timer can provide a cellular Internet connection to the control (See Internet communication ). The BACnet Communication package provides BACnet IP or BACnet MSTP compatibility in addition to the capability of communicating using other protocols when used with a Fieldserver gateway. The Modbus Communication package provide Modbus RTU Communication capability to the SRC Platinum control.

I installed Java. But when I login to the ICMS, I get a Java error. How can I fix that?

You will need to uninstall all the JAVA, JAVA 3D, and JRE upgrades first. For that you will need administrative rights on the computer. Then, download the latest JAVA and JAVA 3D through the ICMS System Requirements webpage. Close all browser windows. Also, make sure that both your Antivirus, and Antimalware are either set to accept the JAVA installation or to be fully turned off. Now you can install the latest JAVA. After the installation is complete install the JAVA 3D. Note that MAC OS 10.7 and later does not support the JAVA 3D.

Connected the control to power correctly but no display or LED is on.

Most controls are equipped with a fuse on the back of the main board to help protect the control against power surges. Check the fuse on the back of the control using a continuity meter. If continuity does not exist, replace the fuse with the same fuse size and rating.

Why doesn’t my Heat-Timer Visual Gold Remote Communication system show the history of the space temperatures?

Question (continued): I can communicate with the system and set any of the panel parameters, but when I go to check how well the system is holding space temperatures, I get only blanks.
To keep a record of the space temperatures (as well as the outdoor temperature and system sensor), the Remote Intercept Platinum or Gold control must know the current time and date. Either the Date and Time were not set or the battery has died and the control power was down for at least a short period of time. Use the SPT (Set Present Time) command. This will prompt for the present date and for the time of day. Once the system has this information, it will keep a log of the histories. If the battery did die, it must be replaced as it keeps the clock active.

Why is my control not turning the boiler on even when there is a call for heat?

First, check the display for any messages as many of the heating controls have several external inputs that can be used to shutdown the boiler. If the message relates to the PROVE input, it may not be shorted or the Prove terminal Jumper is not installed. In this case, the control will not start the boiler. If the message relates to the Shutdown input, the Shutdown maybe shorted remotely. If the message relates to the T-stat input, the T-Stat input maybe opened remotely.

My outdoor sensor reading does not match the actual temperature.

The outdoor sensor measurement may vary based on its location and its sun exposure. In most cases it will never match a weather station that is located several miles away. most current Heat-Timer controls have a Trim feature which allows the sensor reading to be slightly modified just a few degrees to satisfy similar circumstances. If the difference was large, then check the sensor by disconnecting one of its wires from the control. The control should read OPEN. If not, contact technical support.

Why is my temperature sensor reading Open on the control display?

Remove the sensor wires from the control and check for continuity across the wires with and meter. If no continuity existed, check or replace the wires. if continuity did exist, then contact technical support.

Why is my temperature sensor reading Short on the control display?

Remove one of the sensor wires from the control. The control display should change and display OPEN. Then check the sensor wiring specifically around spliced areas. If wiring was good, then disconnect the sensor wires from the control and check the sensor wires with an Ohm meter. The readings should match the sensor temperature chart on the control manual. It not, then replace the sensor. If after removing one of the sensor wires the control read SHORT, then contact tech support.
