You may add the following controls to the OUH2 Space Heater all of these controls if connected as shown in the wiring diagrams
are protected by the heaters internal 3A fuse.
•
OUH2-S
Heater control switch
– Remote way of turning ON/OFF the heater or using it as Fan only in the summer. We
recommend this as a minimum control for your heater. This can either be wall mounted or fixed to the back of the heater
using knockout and screw holes provided.
•
FST2-IN
Frost thermostat
– Overrides all controls including OUH2-S heater control switch “OFF” and turns the heater on
regardless of how OUH2-S is set. This is used to protect the heated area against low temperatures that may cause damage
or freezing of water etc. If used the thermostat MUST be mounted out of direct air flow of the heater and out of reach of
meddling fingers.
•
RST2-IN
Thermostat. Can be used with or without the OUH2-S switch this remote thermostat can be used instead of the
internal thermostat, handy when heaters are mounted high or in positions where access to the internal thermostat is not
easy. Mount out of direct air flow of any heater this thermostat can turn On / Off the system depending on the ambient
temperature. If remote thermostats are used turn up the internal thermostat to full allowing the external t hermostat to control
the heater.
•
RST-TP
Tamperproof Thermostat. Used exactly the same as the RST2-IN but temperature adjustment is concealed.
•
PROSTAT4
The PROSTAT4 thermostat is a highly accurate electronic temperature controller suitable for heavy duty use
in public areas. There are two temperature settings switchable through a push button and integral countdown timer. Optional
remote sensors are available if temperature control is required away f rom the controller.
•
PROTIM-7
7 Day programmable timer. This timer will only allow the heating to operate during the “ON” time settings. During
“OFF” period there is a “Boost” button that with one press allows heating to operate for 1 hour or with 2 presses 2 hours
before turning off. The boost can be cancelled by pressing
the “Boost” button a third time.
•
RT16
Digital Thermostat is a 7 Day, 6/1 Day or 5 / 2 Day programmable room thermostat which offers four time and temperature
changes each day. You may also install a remote sensor if you wish to install the thermostat in a different location to the heaters.
All settings are stored in the controller with battery back-up.
If you connect heaters in a Master / Slave configuration (See Section 6) controls are only added to the master heater and all
the slave heater(s) will follow the master.
