Replacing the WTS battery

1.To determine if battery needs replaced:

a.Navigate to Screen 3 as shown in

Figure 5 (Navigating the Display Menus). If the screen says “REPLACE”, the battery needs replaced.

b.If the OAT Screen (screen 1) reads “AS OF 18:20 AGO” the AWM is not receiving transmissions from the WTS, and the battery should be replaced.

2.To replace battery:

a.Remove old battery from Wireless Temperature Sensor. The lithium battery should be recycled.

b.Press button on Wireless Temperature Sensor once. This step is extremely important to make sure the power from the old battery is depleted so that the sensor will know it has a new battery.

c.Insert new 3.6V lithium battery. See Technical Speciﬁcations Section for battery speciﬁcations and replacement part number. Make sure battery is inserted properly (see polarity mark on battery holder).

Installing a new AWM or WTS

1.If the pre-linked AWM or WTS must be replaced for any reason, the new pair of devices must be linked before use. Follow the steps below to link the new devices.

2.Installing a new AWM

Remove power from the AquaSmart control. Remove the old AWM from the control by gently squeezing the sides of the device at the indentations marked with arrows and then pull away from the AquaSmart.

a.Snap the new AquaSmart Wireless Module onto the COM Port on the side of the AquaSmart boiler temperature control. Restore power to the control.

b.Clear the old link from the Wireless Temperature Sensor: Hold the button of the WTS for ﬁve seconds. The LED should turn on. Within 5 seconds, press the button once more to conﬁrm the clearing. Once the link is cleared, the LED will ﬂash quickly for 2 seconds.

c.Proceed to Step 4.

3.Installing a new WTS

a.Remove the battery from the old WTS and discard both. The lithium battery should be recycled.

b.In the new Wireless Temperature Sensor, remove the plastic insert on the battery terminal. Make sure battery is inserted properly (see polarity mark on battery holder).

c.Mount the new Wireless Temperature Sensor with the two screws provided at same location as the old WTS.

d.Clear the old link for the AquaSmart Wireless Module: Navigate to Screen 10 as shown in Figure 5 (Navigating the Display Menus). Press ENTER to begin clearing connections, and press ENTER again to conﬁrm.

e.Proceed to Step 4.

4.Linking the AWM and WTS

a.Put the WTS in discovery mode: press the WTS button twice. The LED will ﬂash slowly until it ﬁnds the AWM (for up to 3 minutes).

b.While the WTS is still in discovery mode, put the AquaSmart Wireless Module in discovery mode: Navigate to Screen 9 as shown in Figure 5 (Navigating the Display Menus). Press ENTER to begin searching for new connections. The screen will read “SEARCHING… 3:00” and count down from 3 minutes.

c.Once the AWM sees the WTS, the 4-digit Network I.D. of the WTS will appear on the 2nd line of the AquaSmart’s display. Pressing up or down will cycle through multiple device I.D.s if more than one WTS is found. Press ENTER twice on the AquaSmart display to accept the connection with the WTS. Once the two are linked, the LED on the WTS will ﬂash quickly for 10 seconds and the AquaSmart’s screen will read “CONNECTED: XXXX“, where XXXX is the Network I.D. of the WTS.
