Specifications
Power Supply
• 240VAC + 10% @ 50/60Hz OR
• 24VAC + 10% @ 50/60Hz
• Power Consumption: 7VA Max
When powered by 24 VAC, the operating voltage must meet the
requirements of safety extra low voltage (SELV) to EN 60730
terminals.
Sensor Wiring
1. Do Not connect 24V or 240VAC to “IN+ or IN-” terminals.
2. Screened cable should be used between the sensor and the
MT01. The screen is terminated to the IN- terminal.
3. The temperature sensor is connected between the “IN+ and
IN-” terminals.
Temperature Ratings
• Storage: 0 to 50°C non-condensing
• Operating: 0 to 40°C non-condensing
Enclosure & Mounting
The Innotech MAXTime is housed in a rectangular case suitable for
DIN Rail mounting. The housing is moulded from flame retardant
plastics recognised by UL as UL 94-V0.
Colour: Grey
Dimensions (max): 89mm (l) x 107mm (w) x 69mm (d)
Installation
• The MAXTime should be mounted on DIN rail in cabinets
approved for switchgear or industrial control equipment. It
should be mounted in a dry and clean location, free of excess
vibration. Maximum terminal cable entry is 1.5mm wire.
• Wire in accordance with Innotech connection diagrams and local
bylaws or refer to your local distributor.
Both a 240VAC supply and a 24VAC supply should NEVER be
connected at the same time.
Outputs
• 4 x 10A @ 240 VAC Relays, Normally Open.
Inputs
• 4 x 10K NTC Thermistor / Dry Contact Digital Inputs Thermistor
Input Range: 0°C to 50°C
• The Controller can be configured for use in any one of the four
options shown in the table below:
Interface
The interface of the MAXTime comprises of a 4 line, 80 character
backlit Liquid Crystal Display (LCD) with Directional Cursor Keys,
Escape (#) and Enter keys. A menu system with on-screen user
instructions ensures ease-of-use.
The Default screen of the display shows the current time and status
of all relay channels. Pressing Enter on the keypad will take the user
to the menu system where schedule and configuration changes can
be made. The display always returns to the default screen if no keys
are pressed within two minutes.
The Schedule Menu allows the user to Add, Edit or Delete Weekly
and Yearly Schedules. Weekly Schedules require a Start and Stop
time in Hours, Minutes and Day of Week. Yearly Schedules require a
Date, Month and Year. The Yearly schedule will override all weekly
schedules from 0:00 of the Start Date to 24:00 of the Stop Date. i.e. A
Weekly Schedule for Monday 9:00 to Monday 17:00 on Relay Channel
1 will activate that relay every Monday between 9:00 and 17:00. If
however, a yearly exception schedule set to Start on 2nd September
2002 and Stop on the Same day, will override the Weekly Schedule to
o, since 2nd September 2002 is a Monday.
In addition to the Individual Yearly Schedules for each channel,
Schedules entered into the Master Yearly Schedule will override all
weekly schedules on all channels. This is a convenient way to add
holiday periods to all channels instantly.

Aer Hours
The Aer Hours features can also be accessed from the
Schedules menu. This screen will display the Time remaining for
any channels where the aer hours function has been activated.
The Total accumulated hours of Aer hours usage for each
channel (battery backed log) and the Aer Hours delay can be
adjusted by the user in 15 minute intervals from 15 minutes to 8
hours.
The Aer hours timer cannot be activated if that channel is
currently activated from a schedule. Also, if the Aer hours
timer is triggered prior to the start of a scheduled event, the
Aer hours log will accumulate only for the time used outside
the schedule.
To reset the accumulated Aer hours log for a particular
channel, press and hold the ENTER Key for 5 seconds while
the accumulated time is displayed. The Aer hours log for that
channel will then be reset back to zero.
The Clock Menu allows Setting of the System time and the
Daylight Saving Parameters. When the System time reaches
the calculated Daylight Saving Start Date, the System time will
advance by one hour. When the System time reaches calculated
Daylight Saving Stop Date, the System time will retard by one
hour. Both the System time and Daylight Saving Parameters are
battery backed and will be retained in the absence of a supply
voltage.
The Calibrate menu can be used to view the measured
temperature when a thermistor is connected to any of the input
terminals. The measured value can then be adjusted by an oset
value which will change the measured temperature as seen by
the optimum start algorithm.
Optimum Start
The Optimum start (OptStart) menu is used to configure parameters and
enable/disable the optimum start control algorithm. When enabled, the
optimum start will aect all schedules for that channel. The optimum
start parameters are:
1. Setpoint
Desired temperature to be achieved at occupied time (scheduled
start time).
2. Alpha
A smoothing filter applied to changes to the optimum start output.
3. Deadband
This defines the total temperature deadband.
4. Heat Value
This is a parameter of the building the optimum start is used in.
The optimum start uses this value to estimate the time required to
start heating before scheduled time. Each time the optimum start
runs, it will recalculate this value and apply the alpha value from
parameter 2. This parameter is in °C/Hour since it is the number
of degrees Celsius that the air conditioning plant can heat the
building within one hour.
5. Cool Value
As per Initial Heat except applies to cooling.
6. Maximum Prestart
In minutes - This is the maximum number of minutes the optimum
start is allowed to start before the scheduled time.

1. Never touch the I/O terminals while power is being supplied.
2. Never attempt to disassemble the unit while power is being supplied.
3. Emergency stop circuits, limit circuits, interlock circuits and similar safety measures must be provided.
4. The TIMESWITCH outputs may remain On or O due to burning or deposition of the output relays.
External safety measures must be provided for such problems to ensure safety in the system.
5. Follow Innotech wiring diagrams and the installation / wiring instructions contained in this Datasheet.
