Wired Remote Temperature Sensing

Wired Remote Temperature Sensing

One remote temperature sensor can be installed indoor or outdoor and connected to the thermostat by a maximum cable length of 100 meters (300 ft).. Three terminals, +, S & - are provided on the terminal block to connect to the White- Rodgers standard wired remote sensor.. This sensor will be read by the thermostat only when 24VAC is present..

When used as indoor sensor, the readings can be weighted with the local sensor for specific program periods. User can enable or disable the remote sensor in the installer configura- tion mode and also the outdoor temperature can be selected to show on the display..

Once in the installer configuration mode, momentarily press the Weight of Remote Reading: or Manual background touch key until display indicates Remote (at the top left of the LCD) and OFF (default – in clock digits)..

Pressing Manual background or Manual background touch key will toggle the operation and display from Remote OFF to Remote On..

When Remote On is selected, press Manual background key for the display to indicate Remote In (for indoor remote)..

The Manual background or Manual background keys will toggle the operation and display from Remote In to Outdoor Remote..

When any remote is selected the temperature will display in the clock digits for one second alternating with the current time for three seconds when in Run Schedule mode.. Outdoor Remote will indicate at the top left of display for outdoor remote reading..

Only Remote will show at top left for indoor remote reading.. (oF or oC will not indicate with remote temperature readings)..

Sensing Range:

Outdoor temperature range is -40 to 140oF Indoor temperature range is 32 oF to 99 oF

PROGRAMMING

Weight of Remote Reading:

When in view schedule mode the weight of the indoor remote sensor will be shown in the left actual temperature digits des- ignated as A2 (default for average weight), H4 (high weight) or L1 (low weight).. The period (Morning, Day, Evening, Night) will also be shown to the right of the weight value in the actual temperature digits..

When in view schedule mode, press Manual background and Manual background keys at the the same time to sequence the indoor remote temperature sensor weight from A2 to H4 to L1 and back to A2 for each of the program period times for each day.. (The H4 weight is twice the weight of A2 and A2 is twice the weight of L1)..

When Remote In is selected (with Remote selected to On), press Manual background key for the display to indicate the status of the local sensor LS On (default for thermostat local sensor operation- al).. The Manual background and Manual background keys will toggle the function and display from LS (shown in actual temperature digits) and On (shown in clock digits) to LS OFF to designate the local sensor is disabled..

The local sensor may be disabled only if the indoor remote sensor is enabled and functional..

If the indoor remote sensor is disabled or not functional, the local sensor will automatically enable and display in the run schedule mode..

The actual temperature displayed in the run mode is the mathematical weighted sum of the two temperature sensors – local and indoor remote..

(Outdoor remote sensor is not used for this computation)..

If the remote sensor is absent or not enabled then the actual temperature will be as measured by the local sensor..
