◇

Expansion valves

¥ The expansion valves are initialized when power is supplied. The valve for unit 1 is fully closed (520

pulses), and then that for unit 2 is fully opened (480 pulses). When the valve for unit 1 is fully closed (0

pulse), start-up is possible.

¥ The start openings are held during the steady speed period when the compressor is started. After the

steady speed period is finished, the TD control is entered. The start openings are set to PSTARTH when

the outdoor temperature at start 40ûC or more, and to PSTART when it is less than 40ûC.

◇

Compressor rotation speed

¥ When the compressor is started, the SDRCT1 speed / TSTKTM1 second is held.

After the steady speed period is finished, the speed increases at the rate of SDSTEP speed / TSKSPT

second until the target speed is reached.

¥ See other sections for details of expansion valve TD control, ÆN correction and distribution control.

¥ TSKTM1, SDRCT1, SDSTEP, TSKSPT, CMAX2, PSTART and PSTARTH are EEPROM data.

¥ Unit 3 and 4 operation is the same as unit 1 and 2.

However, the outdoor unit fan is operated with the type A compressor.

¥ Wiht RAM-70QH4, type B compressor operates unit 3 only.
