SenseAir TSENSE VAV No Disp Manual de usuario

CO2-, temperature- and

relative humidity controller

General

tSENSE VAV No Disp for wall mounting measures indoor air carbon dioxide concentration,

temperature and relative humidity in rooms. The unit connects to Direct Digital Control (DDC).

Linear outputs are pre-programmed as CO2-, temperature- and relative humidity controller. Output

parameters can be modified from PC (Windows) software UIP (version 5 or higher) and USB

communication cable, alternative via Modbus or BACnet.

Figure 3: Screw Terminal

The sensor is supplied with 0 - 10VDC linear analogue outputs for Out(1), Out(2) and Out(3) (see

Table 1). Alternative output ranges can be configured via PC software UIP (version 5 or later). See

information at senseair.com.

Out1/Out2/Out3

e.g

Each output consists of four blocks. Each block has nine source options.

OUT1 (OUT2/ OUT3/(Relay)) is the largest (Max of a, b , c) demand from Proportional-bands.

OUT1=Max of Out1_a/ Out1_b/ Out1_c minus (sub) Out1_d

5V (Out1_c) –0V (Out1_d Disabled) = 5V => OUT1=5V

The (e.g.) VAV valve opens from minimum set-point position with full opened state at the maximum

set-point.

UOut = 0V

if space has the value:

UOut will be increased

if space has the value:

UOut = 10V

if space has the value:

CO2≤ 600ppm

and

Temp ≤ 22°C

and

RH ≤ 75%RH

(Out1_d = Disabled)

600ppm ≤CO2< 900ppm

22°C ≤Temp < 23°C

75%RH ≤RH < 85%RH

(Out1_d = Disabled)

CO2> 900ppm

Temp > 23°C

RH > 85%

(Out1_d = Disabled)

e.g. Temp protection (Out1_d) Enabled

OUT1 =10V (Out1_a) –10V (Out1_d) =0V

Out1_a: CO2has a Proportional-band of 600-900ppm

Out1_b: Temp has a Proportional-band of 22-23°C

Out1_c: RH has a Proportional-band of 75-85%RH

Automatic system test

A full system test is executed automatically at every power-up. Sensor probes are checked constantly

during operation against failure by checking valid dynamic measurement ranges.

System checks returns error bytes to RAM. Error codes are available by connecting the sensors to a

PC with a special USB cable (art.no. 00-0-0070) connected (see fig. 2). Error codes are shown in

software UIP (version 5 or higher) at “Meter information - Error Flags””
