PID or Oversize (Control Logic) • T he HWRQ Platinum can use an algorithm (PID) to look at the rate of change in the System. If the System Temperature changes quickly, the HWRQ Platinum will turn on or off stages quickly. If the temperature changes are slow or minor, the HWRQ Platinum will react slowly. The PID logic provides the most stable operation. Stages are brought on or off based on the rate of change of the System Temperature and the impact a stage has on that rate. • F or applications where the stages are oversized for most load conditions, the HWRQ Platinum has Oversize System logic. The Oversize logic turns stages on or off proportionally, based on how far the System Temperature is from the Set Point. Water Offset The Offset value moves the starting point of the Reset Ratio curves. Therefore, any change made to the Offset will immediately change the value of the Target Water Temperature (TGT) by the same amount. For example, if the Target Water Temperature (TGT) was 150°F based on the specific outdoor temperature and Reset Ratio, then increasing the Offset from 0°F to 10°F would increase the Target Water Temperature (TGT) to 160°F. In a new installation, start with an Offset value of 0°F. Adjust the Offset value in mild weather. If the ambient indoor temperatures are too warm in the mild weather, decrease the Offset. If the ambient building temperatures are too cold in the mild weather, increase the Offset. The rule of thumb for baseboard radiation is to change the Offset by 4°F for every 1°F degree you wish to change the building temperatures. For radiant heat applications, change the Offset by 1° or 2° for every degree you wish to change the building temperature. The Offset can be set from -40 to 40°F. Setback Whenever the Outdoor temperature (OD) falls below the Outdoor Cutoff, the system pump is activated and the HWRQ Platinum regulates the heating system to hold the Computed Water temperature. As the Outdoor temperature (OD) changes, the HWRQ Platinum adjusts the actual water temperature to hold a constant Day (Normal) heat level. The Day heat level is for when occupants are present and active. The HWRQ can also hold a lower or Night (Setback) heat level. This lower level of heat is for when the building is unoccupied or tenants are sleeping. The HWRQ has the capability of programming up to 4 Day and 4 Night settings for each day of the week. When the building comes out of Night setting, there is an optional Boost setting to quickly bring the building up to comfortable temperatures. HWRQ Platinum Installation and Operation Manual... - Page 8 • I f the domestic hot water is set to have priority, the system Pump relay will turn off for up to an hour or until the DHW Call terminates, whichever is sooner. Upon termination of DHW Call, the HWRQ Platinum will revert to its operating schedule and logic. Schedules • B y setting an operating Schedule and Night Setback, you can save energy while providing comfortable heat to the building. The setting allows the HWRQ Platinum to reduce Target temperature (TGT) by a specific number of degrees set by the Night Setback during the night or when building is unoccupied, i.e. office buildings and schools. • D uring the day, Day Time settings will change Target temperature (TGT) based on Outdoor temperature (OD), Water Offset, Reset Ratio. A Night Time setting will reduce the Target Temperature by the Setback setting. Each weekday can have up to 4 Day Time and 4 Night Time (Setback) settings. Refer to Schedules (menu selection), and System Settings/System Settings 2/Night Setback (menu selection).

Setback. Refer to System Settings/System Settings 2/Boost Mode (menu selection) System Pump Run-On • T his feature lets the HWRQ Platinum run the System Pump for a longer period after the boilers have been turned off, consequently, dissipating the excess heat from the boilers combustion chamber. That way the boiler should not over heat and activate its high limits. Refer to System Settings/Sys Run-On (menu selection) Remote Communication • T he HWRQ Platinum can be upgraded to Internet, BACnet IP, BACnet MSTP, or MODBUS communication to monitor and control all HWRQ Platinum functions from a remote location. Only, the Internet communication package upgrade allows the HWRQ Platinum to accept additional sensors, to monitor their status, and to provide alarms if the sensor values are not in the correct range. MAKING SURE YOU HAVE THE RIGHT CONTROL If you need the HWRQ Platinum to do additional tasks that either is not listed or do not know how to configure them, contact Heat- Timer Corp. Sales Department either by Phone (973)575-4004, Fax (973) 575-4052, or by E-mail support@heat-timer.com. HWRQ Platinum Installation and Operation Manual... -

(Available with Reset Control Mode Only) -40°F to 40°F Default: 0°F SELECT Settings/System Settings/Target Offset • T he Target Offset setting lets you adjust the starting points of the Reset Ratio curves. This means that, regardless of the Outdoor temperature (OD), or the Reset Ratio that has been selected, when the Offset setting is changed, that change is directly added or subtracted to the Target water temperature (TGT). For example, if the Target water temperature (TGT) was 130°F and the Offset was changed from 0° to 10° (an increase of 10°), then the Target water temperature (TGT) would increase to 140°F • T he Target Offset setting does not change the effect that Outdoor temperature (OD) has on System water temperature (SYS). For instance, with an E setting (1.00 (OD):1.00 (SYS)) Reset Ratio, the System water temperature (SYS) will always increase one degree for each degree change in the Outdoor temperature (OD). What the Offset does is add or subtract a constant temperature value. (See Understanding Operation Concept) • I f required: Adjust the Water Offset in mild weather. If the ambient building temperatures are too warm in the mild weather, decrease the Water Offset. If the ambient building temperatures are too cold in the mild weather, increase the Water Offset. The rule of thumb for baseboard radiation is to change the Offset 4°F for every 1°F you wish to change the building temperatures. In radiant heat applications, change the Offset 1°F or 2°F for every 1°F you wish to change the building temperature. HWRQ Platinum Installation and Operation Manual... -

• T he Pump relay will energize whenever the Outdoor temperature (OD) is below the Outdoor Cutoff (CUT). When the Outdoor temperature increases 2°F above the Outdoor Cutoff after the last burner stage relay has de-energized, the Pump relay will stay on for a period of time set by the Pump Run-On. This allows the Pump to dissipate the residual heat within the boilers back into the building. • T he Pump Run-On time should be set based on the size and type of the boilers. A boiler with low water content and high horsepower will need a longer Pump Run-On than a boiler with the same horsepower but has more water content. - MIN TARGET TEMP -- MINIMUM TARGET 80 F 70°F to 170°F Default: 80°F SELECT Settings/System Settings/More Settings/Minimum Target • T he Minimum Water Temperature must be set to the boiler manufacturer’s specification. The HWRQ Platinum will calculate the Target temperature (TGT) based on the Outdoor temperature (OD), the Reset Ratio, and the Offset value.

3667 2914 To perform the test, you will need a digital multi-meter capable of reading resistances. The Heating 2332 System Sensor and Outdoor Sensor temperatures are constantly displayed on the HWRQ Platinum. 1879 Remove the outdoor sensor wires from the Out Temp terminals (A11 and A12), or the heating system sensor wires from System Temp terminals (A1 and A2). Use the multi-meter to take a resistance 1524 reading across the detached wires going to the sensor. If the reading shows: 1243 1021 • O PEN or resistance is higher than the values on the adjacent chart - Check the wires going to the sensor. They may have been broken or become disconnected. If the wires are fine, check the resistance at the sensor itself. If the resistance is still open, the sensor has been damaged and needs to be replaced. • S HORT or resistance is lower than the values on the adjacent chart - Check the wires going to the sensor. They may have become shorted together in the run of the wire. If not, check the resistance at the sensor itself. If there still is no resistance, the sensor has been damaged and needs to be replaced. • R esistances from 187 ohms to 117720 ohms - Find the temperature that corresponds to the resistance value on the chart. If the sensor appears to be outputting correctly, check that the wires were properly connected to the HWRQ Platinum inputs. If the sensor is not outputting correctly, take another reading at the sensor itself. If this is correct, the problem is in the wiring SHORT between the sensor and the HWRQ Platinum. Otherwise, the sensor has been damaged, and should be replaced. HWRQ Platinum Installation and Operation Manual... -
