|
| The current limit is the maximum current demand allowed on any phase at any |
|
|
|
| time. Limiting the unit’s current (amperage) reduces the load on the main power |
|
|
Cd32 | Current Limit | and lowers the compressor discharge pressure. When desirable, the limit can be |
|
|
| (Amperes) | lowered. Note, however, that capacity is also reduced. The five values for 460vac |
|
|
|
| operation are: |
|
|
|
| 15, 17, 19, 21 (Factory Default), 23 |
|
|
|
| This code is only applicable to units with a humidity sensor (HS).Relative humidity |
|
|
|
| set point is available only on units configured for dehumidification. When the |
|
|
|
| mode is activated, the control probe LED flashes on and off every second to alert |
|
|
|
| the user. If not configured, the mode is permanently deactivated and Cd33 will |
|
|
| Dehumidification | display |
|
|
Cd33 | Control (% RH) | to 95% relative humidity in increments of 1%. If bulb mode is active (code Cd35) |
|
|
| (Optional) | and “Lo” speed evaporator motors are selected (code Cd36) then set point |
|
|
|
| ranges from 60 to 95%. When “TEST” is selected or test set point is entered, the |
|
|
|
| heaters should be turned on, indicating that dehumidification mode is activated. |
|
|
|
| After a period of five minutes has elapsed in this mode, the previously selected |
|
|
|
| mode is reinstated. |
|
|
| Economy Mode | Economy mode is a user selectable mode of operation provided for power saving |
|
|
Cd34 | purposes. Refer to sections 3.1.7.1 and 3.1.7.2 for a more detailed description of |
|
| |
| economy mode. |
|
| |
|
|
|

|
|
|
|
|
|
| Bulb mode is a user selectable mode of operation that is an extension of normal |
|
|
| Bulb Mode | dehumidification. If dehumidification is set to “Off,” code Cd35 will display “Nor” |
|
|
| and the user will be unable to change it. After a dehumidification set point has |
|
| |
Cd35 |
|
| ||
been selected and entered for code Cd33, the user may then change code Cd35 |
|
| ||
| (Optional) |
|
| |
| to “bulb.” After bulb has been selected and entered, the user may then utilize |
|
| |
|
|
|
| |
|
| function codes Cd36 and Cd37 to make the desired changes. |
|
|
|
|
|
|
|
|
| This code is enabled only if a dehumidification set point has been selected using |
|
|
|
| function code Cd33 and “bulb” has been selected using function code Cd35. If |
|
|
| Evaporator Speed | these conditions are not met, “alt” will be displayed indicating that the evaporator |
|
|
| fans will alternate their speed whenever a dehumidification set point is selected. |
|
| |
| Select |
|
| |
Cd36 | This display cannot be changed by the user. If a dehumidification set point has |
|
| |
| (Cd35 must be in | been selected along with bulb mode then “alt” may be selected for alternating |
|
|
|
|
| ||
| “Bulb”) |
| 3 | |
| speed, “Lo” for low speed evaporator fan only, or “Hi” for high speed evaporator |
| ||
|
|
| SECTION | |
|
| fan only. If a setting other than “alt” has been selected and bulb mode is |
| |
|
|
|
| |
|
| deactivated in any manner, then selection reverts back to “alt.” |
|
|
|
|
|
|
|
|
| This code, as with function code Cd36, is used in conjunction with bulb mode and |
|
|
|
| dehumidification. If bulb mode is active, this code allows the user to change the |
|
|
| Defrost Temperature | temperature above which the defrost termination sensor (DTS) temperature must |
|
|
Cd37 | go to terminate defrost. It allows the user to change the setting from 4_C to |
|
| |
Sensor Setting | 25.6_C in 0.1_C (0.2_F) increments. This value is changed using the UP/DOWN |
|
| |
| (Optional) |
|
| |
| ARROW keys, followed by the ENTER key when the desired value is displayed. If |
|
| |
|
|
|
| |
|
| bulb mode is deactivated in any manner, the DTS setting above which defrost |
|
|
|
| terminates defaults to the normal 25.6_C (78_F) setting. |
|
|
|
|
|
|
|
|
| NOTE |
|
|
In the unlikely event that AL55 activates, Function Codes Cd38 and Cd39 will display SRS and RRS, |
|
| ||
respectively. |
|
|
| |
|
| This code is only applicable to units without a DataCORDER that are configured |
|
|
| Secondary Supply | to have four probes. If this is true, it will then display the current secondary supply |
|
|
Cd38 | Air Temperature | air temperature.If the unit is configured with a DataCORDER, the Controller |
|
|
| (Optional) | function code Cd38 will display |
|
|
|
| appear on the DataCORDER function code dC1. |
