Wireless Temperature Module

Model 7600WTM

Wireless Outdoor Temperature Reset

Description / Applications

The Beckett AquaSmart® Wireless Temperature Module (WTM) is a 2-part accessory for the AquaSmart boiler control. It adds outdoor reset capability to the AquaSmart control by overriding the control’s built-in HeatManager algorithm when installed. The wireless feature makes installation easy by eliminating mounting location limitations for the outdoor sensor and the need to run wires outside.

Outdoor Temperature Reset (OTR) settings like reset ratio and boost have been made easier to adjust and are accessible through the AquaSmart control’s backlit LCD digital display. The WTM is backwards-compatible with all existing AquaSmart controls. The WTM may provide additional fuel savings over the built-in HeatManager algorithm with the addition of a warm weather shutdown feature that can disable the low limit. It is ideal for installations with high indirect domestic hot water demands or a large water mass (such as radiant in-ﬂ oor heating).

NOTICE

Non-intended usage can cause damage to the WTM or the control being connected to and potentially alter control or system operation.

This device is only for use in the United States and Canada.

Approvals

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy, and if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment OFF and ON, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna.

Increase the separation between the

2. equipment and receiver.

Connect the equipment into an outlet on a

3. circuit different from that to which the receiver is connected.

Consult the dealer or an experienced radio/

4. TV technician for help.

This device complies with Industry Canada license - exempt RSS standard(s). Operation is subject to the following two conditions: (1) This device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device.

Le présent appareil est conforme aux CNR d’Industrie Canada applicables aux appareils radio exempts de licence. L’exploitation est autorisée aux deux conditions suivantes: (1) l’appareil ne doit pas produire de brouillage, et (2) l’utilisateur de l’appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d’en compromettre le fonctionnement.

To satisfy FCC RF Exposure

requirements for mobile and base station transmission devices, a separation distance of 20cm (8”) or more should be maintained between the antenna of this device and persons during operation. To ensure compliance, operation at closer than this distance is not recommended.

The antenna(s) used for this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.

Operation

The Beckett 7600AWM (AquaSmart

○

Wireless Module) dynamically adjusts the boiler high setpoint using the graph shown in Figure 1 and inputs of the outdoor temperature and user-conﬁ gurable setpoints as noted in the ﬁ gure.

○

The WTM algorithm overrides the HeatManager AquaSmart when enabled. If the outdoor sensor battery is depleted or if the sensor stops working for any reason, the AWM will revert the AquaSmart back to its HeatManager can be replaced.

○

In normal operation, the WTS sends the AWM the outdoor temperature every 10 60 minutes. Pressing the WTS button once forces a transmission.

functionality of the base

The Beckett 7600WTM can help to

○

achieve even greater fuel savings over the base AquaSmart with the following advanced features:

Warm Weather Shutdown can be

enabled to turn the low limit (if used) off if the outdoor temperature is above 70°F.

The boost function can be adjusted in

small increments to prevent the reset algorithm from being overridden too quickly, which can beneﬁ t systems with high water mass (such as in-ﬂ oor radiant heating applications).

The outdoor reset algorithm begins

economizing immediately after a Domestic Hot Water (DHW) call for heat, where the HeatManager takes time to reach full economizing after a DHW call.
