Single Boiler or Motorized Valve Hydronic/Hot Water Outdoor Reset Heating Controls
Available with optional Internet , BACnet, or Modbus communication
The HWR Platinum is an outdoor reset boiler or motorized valve heating control. The HWR Platinum will start and stop the boiler and modulate a motorized valve, to vary the system water temperature in a buildings radiation in accordance with changes in outside temperature based on the Outdoor Reset Ratio settings. Unlike other outdoor reset controls that uses the space temperature to shutdown the the system, the HWR Platinum monitors the space temperature over a time period and uses that data to help reduce temperature fluctuation in the building.
In addition to building heating, the HWR platinum offer Domestic Hot Water Priority. Add to that its capability of controling the domestic hot water pump.
The HWR 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 HWR Platinum control.
With its 80 character alphanumeric display and easy-to-use menu structure, changing settings is a snap. In addition, it incorporates Shutdown and Prove inputs for EMS capability.

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.
My hot water outdoor reset control is giving me too much heat. What should I do?
Check if the control has any of the following: •Reset Ratio and Offset – If excessive heat occurs only in certain weather conditions, adjust the Reset Ratio and Offset. If excessive heat occurs year round, reduce the Offset. •Boiler Mode Settings – The control will only operate boilers their mode is set to Auto or Standby. Check to if any boiler stage is set to Manual or On. •Multi-Stage Control Settings – The Last-Stage-Hold will allow only the Lead boiler to stay on for an additional number of degrees. If the setting is too high, and only the Lead boiler is on, the system can over heat. Reduce the Last-Stage-Hold setting. •Domestic Hot Water Call – On a DHW call, the System Set Point will rise to the DHW Set Point or 200°F. If the increase in temperature is during DHW call, see about using any of the DHW Priority options available on the control.
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.
Why does my Heat-Timer hot water reset control (HWR) flash OPN instead of the outdoor temperature?
Heat-Timer controls use the code OPN when they can not detect a sensor. For example, if someone were working in the building and cut the wires leading to the outdoor sensor, the HWR would begin to flash OPN to signal that the sensor was no longer attached. To find the source of the OPN reading, first make sure that the outdoor sensor wires are attached to the input terminals (the IT terminals in the case of an HWR). Then place a jumper wire across the input terminals (IT). The display should change to read SH-I (the code for a shorted sensor). If the display does change, the HWR is working properly. Check the wires to make sure they are not broken, and locate the sensor to see if it has been damaged.
