100W DC48V TEC AIR CONDITIONER
Model: TC06-10TEH/01

1. Introduction
 
The TC06−10TEH/01 TEC air conditioner is a full automation temperature control device. It uses intelligent controller to control the whole system of the air conditioner. According to the variation of environment temperature, the intelligent controller can automatically detect and operate . The product is widely applied in telecom cabinet, small and medium sized telecom room, UPS room, outdoor base station room, etc.

2. Technical Specs
2.1 General Description
 
The TC06−10TEH/01 TEC air conditioner consists of 6 parts: peltier module (including sealing and insulation material), cold end radiator, hot end radiator, cold end fan, hot end fan, monitoring module. When power supply is connected to the TEC, one side of the peltier conduct cooling, and the other side of the peltier conduct heating, the cool (heat) from which will diffuse to the surrounding environment through cold (hot) end radiators and fans. The cold end radiator and cod end fan constitute the inside circulation for cooling the cabinet internal environment, while the hot end radiator and hot end fan constitute outside circulation for heat radiation to the external environment.

Both the inside circulation and outside circulation air ducts adopt air inlet through middle fans and air outlet through radiators at the two sides.

3.3.1 Buttons

PgDn:page down button, confirm button.

Press once and release the button, select next parameter;

A long press on the button, enter or exit parameter mode.

▲：At parameter mode: increasing parameter revision. At operating mode: press this button to enter manual cooling mode (manual cooling preparation mode, with cooling indicator flashing), start manual cooling together with PgUp button.

▼：At parameter mode: decreasing parameter revision. At operating mode: press this button to enter manual heating mode (manual heating preparation mode, with heating indicator flashing), start manual heating together with PgUp button.

PgUp: At parameter mode:dispaly parameter name and parameter value. At operating mode: if previously it is manual cooling preparation mode, press this button to enter manual cooling mode; if previously it is manual heating preparation mode, press this button to enter manual heating mode.

3.3.2 Operating Instruction

(1) Operating Mode:

The mode is normal working mode. 3 digits LED display measured temperature and set temperature in turn. Six LED meanings:

PV lamp on: the digital window displays measured temperature;

SV lamp on: the digital window displays set temperature; at cooling mode, it shows cooling start temperature; at heating mode, it shows heating set temperature;

Col lamp on: the current output is cooling; flashing means manual preparation mode;

Heat lamp on: the current output is heating; flashing means manual preparation mode;

TEC alarm on: TEC failure, fan failure, or temperature sensor failure;

Temp alarm on: measured temperature is higher than set upper limit or lower than set lower limit.

At operating mode, a long press on PgDn to enter parameter mode, or manual cooling/heating mode. Please refer to 3.3.1.

(2) Parameter Mode:
 
At this mode, one can observe or revise the revisable parameters. Refer to 3.3.3 parameter instruction.

At parameter mode: one can manually shift parameter no.(Pn) or parameter value display (shift with PgUp button).
