Non Programmable Thermostat / Air Conditioner With Thermostat In AC

Name: Non Programmable Thermostat / Air Conditioner With Thermostat In AC
Brand: Smart Therm

OCTK305AC is a 230 VAC non-programmable thermostat for fan coil units and room air conditioning, with a display accuracy of +/-0.5 C. That is tighter than the +/-1 C typical of this class, which matters where a specification sets a narrow comfort band. The switching side uses an Omron relay and the housing is flame retardant ABS, weighing 150 g.

Key Benefits

+/-0.5 C display accuracy, tighter than most FCU room controls
Omron relay on the switching side for a documented contact life
230 VAC supply removes the need for a control transformer
0.5 C setpoint steps between 5 C and 35 C
Flame retardant ABS housing at 150 g, easy to handle on a large fit-out

Problems It Solves

Comfort bands wider than the specification allows
Unnamed relays making contact life unpredictable
Extra transformers needed for low voltage controls
Programmable stats being reprogrammed by occupants

Comparison

How It Compares

OCTK301AC

OCTK305AC specifies a +/-0.5 C display accuracy and an Omron relay, which suits projects with a tighter comfort tolerance.

Battery powered room stats

The 230 VAC supply means no batteries to change across a building full of fan coil units.

Use guide

Installing And Commissioning

Step 1

Isolate the 230 VAC supply before opening the FCU terminal box

Step 2

Mount at about 1.5 m clear of the supply air stream

Step 3

Land the conductors on the marked terminals

Step 4

Select HEAT or COOL and set the target temperature in 0.5 C steps

Step 5

Confirm the coil valve and fan respond within the comfort band
